Specifically, the concept makes use of Digital Beam-Forming (DBF) techniques that are enabled in those systems to provide contiguous azimuth imaging, as in stripmap SAR, but with a fine spatial resolution matching that of a spotlight SAR. The main principles of the concept are analytically derived and experimentally verified in laboratory conditions with calibrated targets, as a springboard for a more in-depth system investigation.eninfo:eu-repo/semantics/closedAccessCo-Located Mimo ArrayMimo SarDbfShort-Range ImagingHIGH-RESOLUTION, CONTIGUOUS SAR IMAGING USING CO-LOCATED MIMO ARRAYS: EXPERIMENTAL PROOF OF CONCEPTConference ObjectWOS:000612224900060
