The ASARS-2 is the Advanced Synthetic Aperture Radar System (ASARS) designed for the US Air Force U-2 aircraft. It provides high resolution radar imagery from long ranges during day or night even with adverse weather. ASARS-2 detects and accurately locates fixed and moving ground targets. It gathers detailed information, formats the data, and transmits high resolution images. The U-2S's ASARS-2 radar sensor is the foundation of other SAR ground mapping radars such as ARL-M, HISAR and Global Hawk.

The ASARS-2B is a new version of the ASARS-2 radar ordered by the US Air Force to outfit the U-2S high altitude reconnaissance aircraft under a $320 million contract. The ASARS-2B is equipped with an active electronically scanned array (AESA) antenna to double the surveillance range compared with the ASARS-2A synthetic aperture radar while keeping the same resolution. The new high resolution sensor completed flight tests in early 2019 and would be ready for deployment in 2020.
