INDUSTRIAL TRAINING ON REPORTER RADAR TRANSMITTER
[attachment=16984]
What actually is RADAR?
.Stands for RADIO DETECTION AND RANGING.
.Is an EM system for the detection and location of reflecting objects.
.Operates by radiating energy into space and detecting the reflected echo signal which determines the target location and information.
.Works on the principle of Echo and Doppler shift.
TYPES OF RADAR
PRIMARY OR SIMPLE RADAR: Primary radar locates an object by transmitting signal and detecting the reflected echo.
Secondary surveillance radar (SSR):
A secondary radar system is basically very similar to
primary but it performs additional features like
controlling of air traffic, identifying the aircraft as a
friend or foe , determining the height of aircraft.
Low Flying Detection Radar ( INDRA II)
Fully coherent system.
Frequency agility.
Pulse compression.
Advanced signal processing using MTD and CFAR Techniques.
Track while scan for 2-D tracking.
Full tracking capabilities for manoeuvering targets.
Multicolour PPI Raster Scan Display, presenting both MTI(Moving Target
Indication) and Synthetic Video.
Integral IFF.
Ease of transportation and fast deployment.
Low Level Light-weight Surveillance Radar for AIRFORCE (Ashlesha)
S-Band 3D Surveillance of aerial targets flying at low and medium altitudes.
Automatic detection and tracking of Fixed wing aircrafts , Helicopter,UAV.
Detection of hovering Helicopters.
Low power consumption and mechanical ruggedness to operate in extreme climatic conditions .
Based on semi active array antenna using the state of art Transmit/
Receive Module (TRM) technology.
Integrated IFF.
Highly modular for quick setup.
Robust EMI/EMC design and good testability/ maintainability features
Separation of CDU from sensor head 750 m.
