ASR 2000

The ASR 2000 is an S-band (2.7-2.9 GHz) airport surveillance radar (ASR) designed for air traffic control, providing aircraft position information within the Terminal Maneuvering Area (TMA) and up to 60 or 80 nautical miles (110 or 150 km) from an airport. Developed as a successor to the ASR 8 and ASR 9, it features a multi-module solid-state transmitter with graceful degradation, offering peak power options of 8, 16, or 32 kW and an operational duty cycle of 6 percent. The system incorporates two redundant wide dynamic range receivers with digital pulse compression (ratio of 18.75 dB) and adaptive moving target detection, achieving a subclutter visibility of 57 dB. Its double-curved parabolic reflector antenna generates a cosecant-squared pattern with very low sidelobes (-28 dB) and offers both vertical linear and circular polarization, meeting ICAO ATC specifications.
