An Image Enhancement Method for Dim Target in Through-the-Wall Radar Imaging

摘要：

This paper mainly deals with the degradation problem of dim target through multi-channel image fusion in image domain, and a method based on depth-first-searching (DFS) algorithm is proposed. To apply this method, Firstly, the target image is formed by back-projection (BP) imaging. Secondly, DFS is used to find the target region automatically. Thirdly, the image of dim target is enhanced according to power proportion, after which a multi-channel image fusion can be applied. Finally, the real data is collected by the stepped-frequency through-the-wall radar, and the processed results demonstrate the method is feasible for dim target imaging.
