Airport long range surveillance radar RL-71SX
General description:
RL-71SX is an Airport Surveillance Radar equipped with fully solid state transmitter intended for detection and control of air traffic in the airport terminal area up to distance of 150 km (80 NM). Built-in of powerful MSSR sub-system with secondary antenna enables to increase radar covering up to 450 km (250 NM). The radar consists of Antenna Unit with radar tower, Radar Head Electronics and Dispatcher Room Equipment. Input radar sub-systems are doubled for reasons of radar reliability increase. Detection / target data processing is utilised own AMTI technology capable of optimal adjustment of radar parameters. Display presentation is provided on large-screen LCD monitors completed by VHF/UHF transceivers and Recording / Reply Unit. Radar system can be supplied through two alternative power sources; short supply drop-outs are covered by installed UPS. RL-71SX standard version includes MSSR Radar Unit fully implemented into radar system.
RL-71SX Radar System uses modular structure enabling possibility to respect customer's wishes. RL-71SX radar system parameters comply with all ICAO and EUROCONTROL recommendations.
