Motion Compensation for SISAR Based on Contrast Maximization
(0) The shadow inverse synthetic aperture radar (SISAR) can obtain the shadow image of the object for target detection, classification and identification. The precise motion compensation is the key problem for the accurate shadow image. A novel method for motion compensation based on the contrast maximization is proposed in this paper. The value of the estimated motion parameter is adjusted continuously until the contrast of the image is maximized. This method is simple and apt for actualization as well as precise motion compensation. Computer simulations are given to illustrate the effectiveness, and the performance of the proposed method with different SNR is also discussed.
