ASARS-2 is operating in X-Band high-resolution multi-mode synthetic aperture radar (SAR). It detects and accurately locates fixed and moving ground targets, gathers detailed information, formats the data, and transmits high resolution images in real time.
The radar is located in the long nose radome. Compared to other reconnaissance variants, this radome has a hump at the top. The prominent radome above the fuselage doesn't contain radar but a satellite communication equipment.
Hughes designed the radar in the early 1980s for the Lockheed U2 TR-1 spy aircraft. Raytheon delivered radar upgrades under the ASARS Improvement Program (AIP), which enhances ASARS-2 capabilities.
