Radar automatic target recognition based on InISAR images

A novel interferometric inverse synthetic aperture radar (InlSAR) imaging method, include an efficient phase unwrapping approach, is proposed, which can work very well under very low signal noise ratio condition. Based on which, an InlSAR image based target recognition method are proposed. The rotation and scale invariant features are extracted from the transformed InlSAR images, namely, the polar images. The simulation results are provided to show the efficiency of the proposed methods. In addition, some system parameters, such as baseline length, target aspect, target speed, etc, are analyzed from the viewpoint of recognition performance.
