Northrop Grumman recently announced that tests aboard a company BAC 1-11 test aircraft have successfully demonstrated the AN/APG-77v1 Active Electronically Scanned Array (AESA) radar’s ability to generate high-resolution, in-flight synthetic aperture radar (SAR) ground maps and moving target tracking. The test flights are the first phase of a planned multi-year contract with Boeing to add SAR capability to the existing fleet of F-22A Raptor stealth fighters, and incorporate them into new production aircraft. SAR capabilities can already be found in most multi-role fighter radars, and current image resolutions for aircraft like advanced F-15E Strike Eagles, F/A-18E/F Hornet Block IIs, et. al. are under 1 meter.
