Detecting moving targets in multiple-channel SAR via double thresholding

Well executed SAR images are picture-like and it is possible to identify various kinds of targets, e.g., trucks, ships, etc. However, from a single SAR image, it is not possible to determine which surface targets are moving. In many applications, it is imperative to detect objects that are moving and track them through stop-go-stop motion. We have developed a technique for detecting moving surface targets in a single frame of multi-channel SAR image using phase-interferometry. In this paper, we present results using airborne SAR data.
