Abstract

Abstract

As a new high resolution ground imaging technique, Circular Synthetic Aperture Radar (CSAR) is capable of long time observation and retrieving the information of the targets. By taking the long time observation advantage, a new moving target detecting method is developed based on the single channel CSAR. Moving target signal model is analyzed with equal range equal Doppler equations, then the method is described. This method regards the original SAR image as combination of two images, one is background without moving target, the other one is foreground with moving target. Because the stationary background changes slower than the moving target signal. Thus median filter can be applied to a sequence of overlapping subaperture SAR images along the time to generate the background image. Next, each original frame is used to subtract the background image. Then the moving targets can be obtained. The proposed method is demonstrated on airborne CSAR moving targets dataset.
