NAVIGATIONAL RADAR

FUNCTION: IT PERFORMS THE FOLLOWING FUNCTIONS ON BOARD: NAVIGATION. COLLOSION DETECTION. DETECTION OF OBSTRUCTION. DETECTION OF ICEBERG. HARBOUR MANEUVERING.

ECHO SOUNDER

Echo sounding is the technique of using sound pulses to find the depth of water.The interval from the emission of a pulse toreception of its echo is recorded, and the depthcalculated from the known speed of propagation ofsound through water. This information is then Typically used for navigation purposes or in orderto obtain depths for charting purposes.

Electronic Steering Gear System

Electronic self-steering is controlled byelectronics operating according to one or moreinput sensors, invariably at least a magneticcompass and sometimes wind direction orGPS position versus a chosen waypoint. Theelectronics module calculates the requiredsteering movement and a drive mechanism(usually electrical, though possibly hydraulic inlarger systems) causes the Rudder to move accordingly.

AEROSPACE ELECTRONICS

TYPES OF ELECTRONIC EQUIPTMENT USED:- AIR TRAFFIC CONTROL RADAR. INSTRUMENT LANDING SYSTEM. GYROSCOPES (STRAP DOWN INS) RADAR ALTIMETER GPS BLACK BOX (FLIGHT DATA & COCKPIT VOICE

RECORDER)

AIR TRAFFIC CONTROL RADAR

FUNCTIONS:- GROUND CONTROL AIR CONTROL (TAKE OFF & LANDING) FLIGHT DATA DELIVERY( CONGESTION) APPROACH & TERMINAL CONTROL (SAFE HAND OVER)

INSTRUMENT LANDING SYSTEM

An instrument landing system (ILS) is a ground-based instrument approach system thatprovides precision guidance to an aircraftapproaching and landing on a runway, using acombination of radio signals and, in many cases, high-intensity lighting arrays to enable a safeLanding during instrument meteorologicalConditions such as low ceilings or reducedvisibility due to fog, rain, or blowing snow.

TYPES OF ILS

CATEGORY 1 (CAT1) for 200ft, min 550m CATEGORY 2 (CAT2) for 100ft, min 350m CATEGORY 3 (CAT3) TYPES OF CAT3:- CAT3 A -for less than 100ft, min 200m CAT3 B -for less than 50 ft, min 50m CAT3 C -no height, zero visibility

GYROSCOPES (STRAP DOWN INS)

FUNCTION:- TO DETECT & CALCULATE HEADING,ROLL & PITCH.

TYPES OF GYROSCOPES:- MECHANICAL RING LASER BEAM MICRO ELECTRO-MECHANICAL

RADAR ALTIMETER

A Radar altimeter measures altitude above theterrain presently beneath an aircraft This typeof altimeter provides the distance between theplane and the ground directly below it. FMCWRadars which use Doppler effect are used asaltimeters.

GPS

FUNCTION:- TO DETECT THE FOLLOWING PARAMETERS:- LATITUDE LONGITUDE SPEED OVER GROUND COURSE MADE GOODFUNCTION: IT USES SATELLITE FEED.

BLACK BOX

A flight data recorder (FDR) (also ADR, for accident data recorder) is an electronic device employed to record any instructions sent to any electronic systems on an aircraft. It is a device used to record specific aircraft performance parameters. Another kind of flight recorder is the cockpit voice Recorder (CVR), which records conversation in the cockpit, radio communications between the cockpit crew and others (including conversation with air traffic control), as well as ambient sounds. In this both functions have been combined into a single unit.

MEDICAL ELECTRONICS

COMPUTER AIDED TOMOGRAPHY MAGNETIC RESONANCE IMAGING ULTRASOUND ELECTRO CARDIOGRAM DIGITAL X-RAY

COMPUTER AIDED TOMOGRAPHY

Computed aided tomography (CAT), is a medical imaging technique employingtomography created by computer processing.Digital Geometry Processing is used togenerate a three dimensional image of theinside of an object from a large series of two-dimensional X-ray images taken around asingle axis of rotation.

MAGNETIC RESONACE IMAGING

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to visualize detailed internal structures. An MRI machine uses a powerful magnetic field to align the magnetization of some atomic nuclei in the body, and radio frequency fields to systematically alter the alignment of this magnetization

ULTRASOUND

ULTRASOUND is an ultrasound-based diagnostic medical imaging technique used to visualize muscles, tendons, and many internal organs, to capture their size, structure and any pathological lesions with real time tomography images. It uses cyclic sound pressure with a frequency greater than the upper limit of human hearing.

ELECTRO CARDIOGRAM

ECG is interpretation of the electrical activity ofthe heart over a period of Time, as detected byelectrodes attached to the outer surface of theskin and recorded by a device external to thebody.

DIGITAL X-RAY

Digital X-RAY is a form of X-ray imaging,where digitalX-ray sensors are used instead of traditionalphotographic film. A high-density line-scan solid statedetector is composed of a photo stimulable bariumfluoro bromide doped with europium (BaFBr:Eu) orcaesium Bromide (CsBr) phosphor. The phosphordetector records the X-ray energy during exposure andis scanned by a laser diode to excite the stored energywhich is released and read out by a digital imagecapture array of a CCD.

DEFENCE ELECTRONICS

RADARS MISSILES ELECTRONIC WARFARE SYSTEM ECM JAMMERS ECCM JAMMERS

RADARS

Radar is an object-detection system whichuses radio waves to determine the range,altitude, direction, or speed of objects. The radar dish or antenna transmits pulses ofradio waves or microwaves which return backEcho signal for any object in their path.

TYPES OF RADARS

Detection and search radars (Surveillance) Targeting radars (WEAPON GUIDANCE) Triggers (Radars inside Missiles) Weather-sensing radar systems Navigational radars Mapping radars Road radar Radars for biological research

MISSILES

A missile is a self-propelled guided weaponsystem. Missiles have five systemcomponents:- Detection & guidance radar, motion sensor ,flight control system,engine and warhead.

TYPES OF MISSILES

Conventional guided missiles Cruise missile Ballistic missile

ELECTRONIC WARFARE SYSTEM

Electronic warfare system refers to systeminvolving the use of the electromagneticspectrum or directed radio energy to control thespectrum, attack an enemy, or impede enemyassaults via the spectrum. It includes three major subdivisions: Electronic Attack,Electronic Protection and Electronic WarfareSupport.

ECM JAMMERS

An electronic countermeasure (ECM)Jammer is an electrical or electronic devicedesigned to trick or deceive radar, sonar orother detection systems, like infrared (IR) orlasers. It may be used both offensively anddefensively to deny targeting information to anenemy.

ECCM JAMMER

Electronic counter-countermeasuresJAMMER (ECCM) is a part of electronicwarfare which includes a variety of practiceswhich attempt to reduce or eliminate the effectof electronic countermeasures (ECM) onelectronic sensors aboard vehicles, ships andaircraft and weapons such as missiles.
