Easat's Primary Surveillance Radar (PSR) systems are optimised for aircraft approach and long-range en-route air traffic applications.

 

Easat PSR radars offer excellent system stability, effective clutter attenuation and elimination of false targets enabling high probability of target detection out to ranges of 120 NM.

 

The high precision dual-beam of Easat's PSR antennas ensures reliable coverage even under severe ground clutter conditions. Advanced algorithms and beam switching techniques mitigate dynamic high-speed clutter, such as wind turbines, trains and road traffic.

 

Easat PSR radars include independent high-resolution weather channels providing precise information on weather conditions (US-NWS 6 level).

 

Easat PSR radars feature advanced modular design, full solid-state technology and comprehensive integrated BITE systems, ensuring low running costs and minimal maintenance requirements.

 

Easat provides complete turn-key solutions, to include a range of antenna tower options, civils works, installation and after-sales service.
