Hmm, if anyone wants to test synthetic-aperture-radar on a drone (with ability to resolve a cell phone), have a target area in Oregon where a family has been looking for someone who went missing in 2020 that just pinged me for help. Satellite imaging is not going to help, too many trees. #SyntheticApertureRadar #SearchAndRescue #RemoteImaging
