Aerodrome radar ASR-22AL

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.

Parameters of transmitted signal as well as parameters of signal processing after reception can be set at the operator workstation, secondary processing and tracking are performed at the remote workstation. Remote workstation can be positioned in a Control Tower. ASR-22/AL can be remotely controlled from Tower.
ASR-22/AL is intended for 24/7/365 operation and is equipped with UPS guaranteeing 10 minutes of operational time in case of mains failure.

All air situation is automatically recorded with playback capability in passive and interactive modes.
ASR-22/AL features efficient protection against pulse interference and active jamming. Level of interference is continuously monitored and graphically represented to the operator. Jamming protection is achieved through expansion of the dynamic range of the signal processor and capability of electronic frequency agility. Passive interference is rejected through digital adaptive MTI and generation of clutter map.
