Abstract : The purpose of 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 describes the radar data collection equipments which were fabricated and emplaced, the data processing equipments assembled, and the data processing software programs prepared for use in subsequent experimentations.
