Thayaparan, K. Mattar and D. Schlingmeier. [Ottawa] : Defence Research and Development Canada, 2014. viii, 10, [2] p. : fig., graphs. Scientific report ; 2014-R5 February 2014. Includes bibliographical references. The current search and rescue (S&R) methods consist of using signals in the visible spectrum to draw the observers’ attention on board overflying S&R aircraft. These existing methods have proven useful but they have inherent limitations such as the requirement for daylight, good weather and relatively restricted areas of operations, due to aircraft range, observers’ fatigue and field of view, as well as 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&R purposes can potentially be useful in designs for emergency gear. gccst Radar Mattar, Karim E.
