摘要：Future high resolution multi-aperture SAR satellites entail high potential for large-area traffi c monitoring from space. While many approaches for detecting across-track moving vehicles in SAR images have already been published within the recent years, the detection of objects moving in along-track is still an issue to be solved. This paper deals with the detection of vehicles, mainly moving in along-track, in high resolution SAR images. The blurring effect caused by the along-track motion component is exploited for this detection scheme. The presented approach is based on a matched filter bank where the SAR image is processed with different matched filters . To extract a particular moving object from the filte r bank, a specialized peak detector is employed. The proposed technique is demonstrated using data of an airborne SAR system (E-SAR from the DLR) and its potential is analyzed
