AbstractThis paper summarizes some results of studies at the Canada Centre for Remote Sensing (CCRS) using Synthetic Aperture Radar (SAR) imagery from spaceborne systems for the detection of crashed aircraft. Studies have been carried out using detected products (intensity values only) and interferometric methods (using complex imagery). Due to the low resolution of single polarization single frequency spaceborne SAR imagery (approximately 8 metres ground range being the best currently available from operational remote sensing satellites), it is seen that such imagery cannot currently be used with much optimism although the techniques themselves show promise. Further study is needed to examine if the better resolutions that will be available from future systems such as RADARSAT-2 make possible the reliable detection of crashed aircraft. Other research, not described in this manuscript, is underway at CCRS through the support of the National Search and Rescue Secretariat examining the contributions to Search and Rescue that can be made using spaceborne polarimetric SAR systems including RADARSAT-2.
