secondaryprimaryfor air traffic

Aerodrome surveillance radar ASR-22/AL is intended for surveillance and air traffic control within terminal airspace. ASR-22/AL combines primary and secondary channels working on the same antenna as well as sidelobe suppression channel for improvement of detection capability. Primary channel of ASR-22/AL operates in L-band (ICAO), secondary channel uses standard frequencies for RBS (interrogation – 1030 MHz, response – 1090 MHz) and Eastern UVD (interrogation – 1030 MHz, response – 740 MHz).ASR-22/AL is structurally divided into two parts and consists of equipment shelter and antenna-feed system with rotary support connected by set of cables.Radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be exchanged over a variety of communication channels in approved format. Radar transmitter and receiver feature solid-state components only. The transmitter has a modular design and provides soft-failure redundancy: failure of individual module leads to partial performance degradation.
