16. Absttuct

A previous aircraft hazard detection algorithm shown to have high detectability butwith a high false alarm rate has been modified to improve reliability for aircraftwarnings. The derived Doppler parameter tangential (or radial' shear is incorporatedas a radar cell attribute and used in the determination of significant hazard. Furthe4modifications to the processi-g structure allow for radar operation in a non-automatic,mode, thereby accomodating arbitrary changes in PRF, integrator type or scan geometry.A revised output format provides a sorted hierarchical list of derived meteorologicalstructures in a form readily adapted to a graphics display.

1. INTRODUCTION

A series of algorithms have been developed that provide automatic

objective analysis of digital Doppler radar data. Crane (1979) described

the radar cell detection and tracking routine that is employed in the

current computer program. Regions of interest observed with the radar are

located by contouring the reflectivity field at the 20 dBZ level. Within

a contour region, relative peaks in the reflectivity or Doppler change

(shear) fields are located and subjected to a multi-threshold contouring

routine. Peak areas that are isolated by a contour which is 3 quantiza-

tion steps (dB for reflectivity) below the peak value are declared cells.

For each cell and contour region a set of attributes is accumulated which

describe the characteristics of that entity. Peak cells detected at

different elevation angles in a volume scan sequence are used to con-

struct three-dimensional volume cell structures over which composite sets

of attributes are accumulated. The volume cell becomes the smallest

resolvable entity in the hierarchy that is developed to characterize the

meteorological situation being observed.

Individual cell motion is established by associating volume cells

detected on successive volume scans and tracking their centroid positions.

Cell association is performed through a comparison of key attribute values

and selection is made through a statistical best match function. The

resultant velocity vectors must conform to a Lagrangian tracking scheme

wherein a more precise track fit is required of longer lived cells.

Closely spaced volume cells that interact are declared clusters and

are tracked as a single entity. Volume cells that have a high reflectivity

and some degree of vertical continuity are considered to be important and

are called significant cells. Isolated significant cells are classified

as clusters that the radar was unable to resolve. The individual cells

enclosed within clusters and contours are used to compute the motion and

other attributes of the larger entities such as their physical extent,

centroid location and lifetime.

At the completion of each volume scan sequence, the computed attributes

compiled over the scan are output. Within the output hierarchy of contours,

clusters and volume cells, each entity is assigned a unique identification

number which it maintains throughout its lifetime. Each cell carries two

attributes that point upward to identify the enclosing cluster and contour

on.

, /

An operational version of the cell detection and tracking routine was

used to analyze non-coherent digital radar data on the Water and Power

Resources Service (WPRS) Cyber-74 computer system (Gustafson, 1980). This

program was initially modified to process Doppler data on the same computer

(Crane, 1981). In the Cyber-74 version, a single Doppler attribute, tan-

gential shear, was extracted and processed to form tangential shear cells.

The shear cells were detected by using the magnitude of tangential shear

in exactly the same way reflectivity cells had been formed using the magni-

tude of the reflectivity level. An identical attribute set was formed for

each type (reflectivity or tangential shear) of cell which was then trans-

ferred to the track routine where the cells were associated without regard

to type.

The Doppler processing routine described in this report is an expan-

sion of the initial operational routines. It is designed to operate on a

VAX 11/780 computer in near real time. The algorithm descriptions in this

report primarily cover modifications to the program versions documented by

Crane (1979) and Gustafson (1980).

2. THE ALGORITHMS AND THEIR USE

2.1 Calibration

Two separate subroutines are available to accept and calibrate raw

integrator data from the radars in Cimarron and Norman, Oklahoma. The

calibration procedure is essentially identical for the two radars, the

only differences being the capability to handle the two formats of the

raw data tapes (listed in Appendix D) and the integrator level/received

power look-up tables. Three parameters are prepared by the calibration

routines which are then passed to the cell detection and trackir,, program,

these are: Reflectivity, Radial Velocity and the Second Moment of the

Radial Velocity (Doppler Spread). A new data set containing pre-calibrated

data in a form directly accessable by the cell detection and tracking

program can be prepared by passing a flag to the calibration routine (refer

to Appendix A). Thereafter, all runs of the program on that data set

should use the routine "EXPAND" in place of the calibration routine in

order to input the prepared data.

Raw radar data tapes contain received power information in the form

of integrator levels set at the radar site. To convert this information

into a reflectivity level in dBZ the integrator level is converted to power

in dBm by a table look-up and then plugged into the equation:

Z= P+ 102 PT +C (1)Z PR 10 log 10 R - 10 log 1 0 T

where Z is reflectivity in dBZ, PR is received power in dBm which is

obtained from the calibration table, R is range in km, PT is traismitter

power in Kw and C is a calibration constant. The computed reflectivity is

then smoothed over a user defined number of range gates (generally two).

The magnitude of the Doppler parameters is extracted directly from the

data tapes and calibrated by Equation (2) for radial velocity and Equation

(3) for Doppler spread:

RV = (LI - R/2) Rv (2)

where RV is radial velocity in m/s, LI is integrator level, R is the range

of integrator levels and Rv is the velocity resolution in m/s.

3

/. . . . . .. . . . . . . . . . . . , . .. . . . .. '

DS = R 2 (1-(1 - I1 2) PR/(PR - N) (3)

where DS is Doppler spread (m/s) , Rs is the spread resolution in m/s, LI

is the integrator level, PR is received power in dBm and N is the average

receiver noise in dBm.

The Doppler information has an inherent frequency ambiguity that the

algorithm will resolve in one of two ways depending on the integrator mode

in use at the time measurements were made. Inthe expanded integrator

mode the Doppler data are collected at a PRF which is four times greater

than that used to obtain the reflectivity data. The correct range

interval is determined through an evaluation of the corresponding reflec-

tivity levels at each of the folded range intervals. Normal integrator

data are collected at a constant PRF and the range interval is determined

by the Nth trip indicator that is operator selectable.

Independent of integrator type, the first few range gates of each fold

(range interval) are eliminated from processing to minimize the effects of

close in ground clutter. Further, each of the three output parameters are

subjected to noise thresholding at each range gate along the radial.

Calibrated data are then passed to the cell detection routine through block

common.

2.2 Contouring and Cell Detection

Calibrated reflectivity data along each radial are contoured through

a nested search routine at two predefined, fixed threshold levels. A base

level of 20 dBZ is used to define regions in the data field within which

the cell detection algorithms will be run. A second user defined level is

available for display purposes only. As each radial of data is contoured

a vector is defined to-connect the contour endpoints on the current radial

to the corresponding endpoints on the prior radial. Each new vector is

assigned the identification (ID) number of any previously defined vector

it connects with. Vector elements tagged with their ID and threshold

level are accumulated in a temporary disk file over the entire azimuth

scan. Similarly, merges and splits of contour segments are stored in a

directory as they occur. After an entire scan has been processed, each

vector ID is passed through the merge/split directory and reassigned a

final contour ID. Vectors with a common contour ID are then linked to

construct a full contour.

4

Within the 20 dBZ contour regions, cell detection is performed

separately on the reflectivity and Doppler data fields. Five Doppler

parameters are available for processing; (1) tangential shear, (2) radial

shear, (3) vector shear, (4) range normalized radial velocity magnitude,

and (5) range normalized Doppler spread (second moment). The magnitude of

the user selected Doppler parameter is quantized into 1-dB steps in order

to be in a form consistent with the reflectivity data. The cell detection

algorithm is designed to locate peak regions in any quantized scalar data

field that are at least 3 dB above the surrounding data and to declare them

peak cells. Reflectivity and quantized Doppler data are processed by two

separate passes through the cell detection routine thereby generating two

peak cell data sets. Each data set is comprised of an identical cell

attribute list (Table 1) describing the characteristics of the individiaul

cells. The cell types are stored separately to allow discriminate process-

ing by the track routine.

2.3 Cell Tracking

At the conclusion of an azimuth scan, the cell detection routine has

produced both reflectivity and Doppler cell attribute lists which are

stored separately. The track routine attempts to associate individual

peak cells to a volume cell track established during prior scans.

In previous versions of the tracking algorithm (Gustafson, 1980), the

azimuth scan sequence was assumed to have been performed in an automatic

mode. For tracking purposes a volume scan was closely defined to be a

series of full azimuth scans made in the same direction; these scans

consisted of a fixed number of constant elevation steps requiring a fixed

amount of time. In order to accomodate data collection in a non-automatic

mode, the volume scan has been more loosely defined to be a series of at

least two azimuth sector scans made in either direction that require

greater than 150 seconds to measure. The cell-to-track association

criteria have been similarly modified to minimize the impact of the data

collection mode on the tracking process.

Of greatest impact is the variability in elevation steps between

azimuth scans that is permitted in the new format. A volume cell is

constructed from the association of individual peak cells detected on

successive scans in a volume scan sequence. A large elevation gap between

scans would normally cause the association logic to reject the new cell

from inclusion in the volume cell structure. However, a relaxation of

the height separation criteria of the association logic to accomodate

large elevation steps could cause invalid associations such as that of

an immature cell at a mid level with the cirrus overhang from a nearby

mature storm. Clearly a trade-off is required; thus, the weight of the

height component of the association function is defined such that a separa-

tion of between 2.5 and 3.0 km will make an association difficult (i.e.

require close agreement between the other components), and a separation

greater than 3 km will cause the association to be rejected.

When a cell-to-track association is successful the volume cell attri-

bute list is updated to include the characteristics of the new cell. A

list of the volume cell attributes is given in Table 2. Determination of

which individual attributes are selected for update depends on the volume

scan sequence and the cell type. The first seven attributes of the list

arc defined on the initial azimuth scan of each volume scan only and are

used as a reference to the cell base. The spatial attributes such as

position and vertical extent are updated on reflectivity cells only.

Doppler cells are themselves considered to be an attribute of the volume

cell, not a part of its physical structure. This is primarily due to the

spatial distribution of turbulent shear regions around an active convec-

tive element (Crane, 1981). The reflectivityand shear peaks are not

generally coincident; rather several regions of high shear may form in the

vicinity of one reflectivity defined radar cell. Therefore, the Doppler

cells contribute to the velocity attributes only. Captions to the right

in Table 2 indicate when each attribute is updated and in which subroutine

the update occurs.

Under one set of conditions the segregation of Doppler cells is over-

ridden. An isolated Doppler peak cell that is detected outside the associa-

tion range of any reflectivity cell is declared a new volume cell and its

position tracked as if it were a reflectivity cell. These isolated Doppler

cells often occur at a location that will, at a future time, produce a

reflectivity cell. Tracking the Doppler cells in this manner yields more

information about the reflectivity cell when it is eventually detected than

if the isolated Doppler cells were discarded.

2.4 Program Output

Data output is generated at the conclusion of each volume scan sequence.

A sort routine creates a direct access binary file that contains a hier-

archical list of all attributes defined or updated on the current scan.

Appendix C provides a complete word description of the output format. A

second formatted summary output is available as a user option (Appendix A).

The sort hierarchy consists of (1) contour regions, (2) enclosed

cell clusters, (3) volume cells contained in clusters, and (4) isolated

volume cells. A two record scan summary is provided as a header, and

sorted contour vector information is appended as a trailer. Vector data

are sorted on (1) contour track ID and (2) threshold level. Table 3 gives

a schematic illustration of the sort file structure. A separate sort file

is created at the end of each volume scan. At the conclusion of a program

run, the individual files should be merged in the order they were created

to produce a sequential record of the processed data (refer to sample

command procedure Figure 4).

The optional formatted output can be configured to provide contour,

cluster, or volume cell attributes, or any combination of these attribute

types. Figure 1 illustrates a sample output displaying all three data

types for one volume scan; the listing sequence is repeated for each volume

scan. Whenever a change in PRF or integrator type is encountered in the

data, the current volume scan is terminated and a radar attribute surmary

(Figure 2) is output.

2.5 Program Organization

The computer program consists of 22 subroutines with flow established

through the main program module "DOPLR8O". Figure 3 (a,b) illustrates

how control cascades through the subroutines during one volume scan

sequence. Note that subroutines PEAKD and COMPARE process reflectivity

and Doppler data separately and each require two calls. The cell detection

process is executed on each radial of data (Figure 3a) whereas the cell

tracking routines are called once at the end of each azimuth scan (Figure 3b).

Each subroutine is stored in a separate file with the common

generic name "FOR". The complete program is stored in an object module

library referenced as "DOPLR8O.OLB". This allows for editing and

recompilation of individual subroutines. The command module "LDOP.COM"

creates an executable image from the object library and should be invoked

just prior to program execution.

2.6 Program Execution

The computer program operates on two types of data; (1) raw integrator

output and (2) calibrated reflectivity, radial velocity and Doppler spread.

Operation on calibrated data requires about 20% less CPU time than raw form.

There are three data input modules available. Two calibration routines

input raw integrator data, perform data calibration, reformat the data, pass

the calibrated data to the cell detection routine, and optionally produce

a calibrated data set. Two routines are required to process data from both

the Cimarron and Norman radars since each generates output in a different

format (Appendix D). Each routine is stored in a file referenced by the

corresponding radar name, CIMARRON.FOR and NORMAN.FOR. The third routine,

in file EXPAND.FOR, inputs pre-calibrated data and passes it directly to

the cell detection routine. EXPAND accepts data from either radar since

the reformatting procedure is identical in the two calibration routines.

Figures 4 and 5 illustrate sample command procedures for processing

raw and calibrated data respectively. DOPTAP.COM (Figure 4) can be run

either interactively or in batch mode. It requires three input parameters,

Pl, P2 and P3. P1 is the label of the tape on which the raw data are stored,

P2 is the file specification for the various output files to be produced,

and P3 is the radar name. During interactive operation the user will be

prompted for each input; in batch mode the input parameters must be

supplied, in order, by a parameter qualifier. For example, the command:

SUBMIT/PARAMETER=(TAPLBL,DATFIL,RADNAM) DOPTAP

will place the job DOPTAP into the batch execution queue and substitute

TAPLBL for Pl, DATFIL for P2 and RADNAM for P3.

After receiving the user inputs the command procedure attempts to

allocate an MTA tape drive. If a drive is not currently available the

procedure waits five minutes and repeats the process until successful.

The operator is requested to load the data tape volume on the allocated

drive and the tape is mounted.

In the LOOP section the disk directory is searched for an existing

file with the same specification and generic name (SRT) as the output file

about to be created. If such a file exists the output file is assigned

the next higher version number. Input files are assigned to a logical

name consisting of "F" plus a number indicating the order in which the

files are to be processed. The number sequence must begin with 1 and be

continuous (Fl, F2, F3...). The output file for calibrated data is given

the generic name PRE and assigned to device FOR002. The integrator-to-

power conversion table for the appropriate radar is assigned input device

FORO04. Formatted summary data output (controlled by PRCELL, PRCLUS and

PRFIXC in subroutine INPARM) is written to a generic file SUM through

device FORO06. Note device FOR006, if left unassigned, defaults to the

user's terminal during an interactive run. Any parity errors encountered

during the tape read are listed in the ERR file assigned FORO07.

The correct calibration routine for the particular radar in use

(e.g ., NORA.NN) is inserted into the object library (1OPLRRO.OLB) by the LIB

command and individual object modules are linked to form an execution

file by the separate command procedure "LDOP.COM". Actual program execu-

tion is performed by invoking the command module RUN DOPLR8O.

Upon completion of the program run, the dita tape is dismounted and

the tape drive deallocated in order to allow access by other users. Two

temporary output files are created after each volume scan, one for the

various contour, cluster and cell attributes and a second for the contour

vectors. These files are merged in the order they were produced to form

a single unformatted, binary file containing a sequential record of the

full observation period. Final bookkeeping involves deleting the

temporary storage files.

A second command procedure is illustrated in Figure 5 which demon-

strates batch only operation on a pre-calibrated data set. In this case,

two input parameters are required; these are: the job name (Pl) for

assignment of output file specification and the radar name (P2). The

calibrated data are stored in a multi-volume tape file that is assigned

to input device FOR002. Note that the integrator-to-power look-up

table is not required since the conversion process was performed during

the earlier run through the calibration procedure. The input routine

"EXPAND" is inserted into the object library in place of the calibration

routine and the program is linked and executed as before.
