Moving Targets Indication Method in a Single High Resolution SAR Imagery Based on Road Information and Shadow Detection

In this paper a novel technique is presented for detecting moving targets in a single high resolution Synthetic Aperture Radar (SAR) imagery based on the imaging characteristics of SAR moving targets. The SAR image of a moving target is blurred and displaced, however, the shadow casted by the moving target is focused and displayed at the actual target location, and the shadow size is the target dimensions. This moving targets indication method is simple, because it is implemented by shadow detection, it is out of the blind speed problem, it is incoherent and uncorrelated with the target direct returning energy. With the road information, the moving targets can be detected, accurately located and the motion parameters can be estimated.
