Joey Cheng writes that DARPA’s broad agency announcement on the Advanced Scanning Technology for Imaging Radars program indicates plans for a single transmit-and-receive chain and an electronic subreflector to enable beam steering.
The produced images would be used in target identification, surveillance and reconnaissance operations amid conditions like bad weather and obstructions to the target such as foliage, the report said.
DARPA identified possible approaches for phase shifters on the subreflector or planar electronically-reflecting surfaces to enable functions beyond those of the Synthetic Aperture Radar and Inverse Synthetic Aperture Radar.
The agency will accept questions regarding the project until Sept. 26 and complete proposals until Oct. 10, Cheng reports.
