Micro Doppler Analysis of a Vibrating/rotating Target in TerraSAR-X Images

Abstract

The current search and rescue (S and R) methods consist of using signals in the visible spectrum to attract the attention of observers within overflying S and R aircraft. These existing methods have proven useful but have inherent limitations such as the requirement for daylight, good weather and relatively restricted areas of operations, due to aircraft range, observer fatigue and the field of view, due to the low altitudes required for a thorough search. The Canadian Forces Joint Imagery Centre (CFJIC), Advanced Exploitation Section (AES) and DRDC Ottawa Research Centre conducted an imagery experiment at Connaught Range to define alternate methods of detecting downed aircrew using space-based sensors such as RADARSAT-2 and TerraSAR-X. Preliminary results demonstrate that the signal-to-noise ratio (SNR) of the target signature is significantly enhanced when the data are analyzed through phase-amplitude comparison of the synthetic aperture radar (SAR) image. These results suggest that the utility of exploiting the unique phase signature of a moving reflector and pendulum for S and R purposes can potentially be useful in designs for emergency gear.
