Weather Forecast Remote sensingLaw enforcementSpace ExplorationShip navigation and safety

Civilian Applications of RADAR

Airspace control

Approach control

Ground control Apron control

Air Traffic Control

Airspace classification

Antennas catering to different Airspace

‘Radome’ L or S band Instantaneous Polarization switching High gain Low sidelobe loss

Antennas for Class A airspace

Antennas for Class B & C airspace

UHF , Omnidirectional or Yagi antennasElevation coverage of 40 degreesCompliant with ICAO specifications

Class D and Ground coverage

‘Radcone’

Aircrafts use on board RADARs for mapping the weather on their course ahead.

Avoid obstacles – terrain on other aircrafts
