Advanced Synthetic Aperture Radar System

Advanced Synthetic Aperture Radar System

Since its inception in the early 1980s, Raytheon’s Advanced Synthetic Aperture Radar System, or ASARS, has served as the intelligence backbone of one of the world’s most heralded high-altitude reconnaissance platforms, the U-2 Dragon Lady.


ASARS  is a high-resolution, multimode, long-range, air-to-ground radar that provides operators with critical intelligence, surveillance and reconnaissance data needed for mission success. Capable of operating in all weather, day or night, ASARS-2 detects and accurately locates fixed and moving ground targets with unprecedented precision.


The newest variant of the system, ASARS-2B, is equipped with an active electronically scanned array antenna. ASARS-2B doubles the surveillance range while maintaining the mapping and imagery resolution of the current ASARS-2A system. ASARS-2B completed flight test at Edwards Air Force Base in California in early 2019.
