This report describes a 13-month program of improvement, repair, and checkout of a Synthetic Aperture Metal Reradiation Reconnaissance Radar System (METRRA/SAR) for the U.S. Army Mobility Equipment Research, Ft. Belvoir, under Contract DAAK70-77-C-0184. The purpose of the system is to detect tactical targets by sensing reradiated third harmonic signals produced by rectification of transmitted pulses at metal-to-metal junctions in the targets. Detection and location are enhanced by synthetic aperture processing of third harmonic signals. The equipment items improved were the transmitter, processor, and scan converter subsystems. The improvements and repairs made were those indicated during flight tests, on a previous contract, which would enhance the performance and reliability of the system. The report details the improvements and repairs made and their effect on system operation. (Author)
