Abstract : The document is the first Quarterly Report for the Synthetic Aperture Helicopter Radar Experimental Evaluation program; it covers work performed between 1 February and 30 April 1969. In scope the program is to determine the resolution and MTI performance of a helicopter radar concept employing rotor tip mounted antennas and real-time digital synthetic aperture processing. The approach involves an experimental evaluation of the concept, via a tower-mounted rotating antenna, to demonstrate performance capabilities and limitations of the concept as achievable in the L-band frequency region. This entails: (1) collecting radar data from the tower-mounted rotating antenna for target and background conditions of interest, (2) recording collected radar data on magnetic tape in a digital format, (3) processing recorded data through a general purpose digital computer to achieve resolution improvement and MTI discrimination, and (4) imaging processed data onto photographic film. The report provides the results of initial design studies for hardware and software required to perform planned experimental evaluations, describes the planned test system and data processing, outlines a plan for experimental evaluations, and summarizes the activities during the reporting period.
