Comparison of RADAR and ADSB

Uses

Interpolation to

time synchronise

ADSB and

Radar Reports.

Position Reports of RADAR /ADSB

Radar position reports are in local polar coordinate

system with Slant height, Azimuth and Flight Level

(ρ,θ,H)

ADSB Position Reports are in Geocentric

coordinate system with latitude, longitude and

Flight level

Co-ordinate transformation

Comparison of ADSB and Radar requires coordinate transformation.

SDA transforms ADSB position reports in Geocentric system to local polar coordinate system of RADAR.

Co-ordinate transformation algorithms prescribed in EUROCONTROL document CAT.017,APPENDIX A: Coordinate Transformation, are used for transforming ADSB position reports to Radar coordinate system.

The same process is used by automation systems to generate single track from multiple surveillance sources

Calculation

The distance between the position reports of ADSB

and RADAR is calculated using the formula

D = Sqrt (r1 2 + r2 2 - 2r1 r2 cos (θ1 - θ2))

Compare RADAR & ADSB

Compare automatically generates ADSB and Radar

reported Position comparison report for a specific

flight. The following details are need to be filled

up for comparison.

2-D Plot Display

It plots the position reports of ADSB & RADAR

simultaneously for visual analysis

Flight path trajectory can be analyzed
