摘要
提出了一种基于图像熵的ISAR运动补偿方法.利用最小熵准则,通过寻优运算得到目标径向运动参数的最优估计,实现对回波数据的运动补偿,从而获得高分辨的目标二维像.仿真结果证明了该方法的有效性.
An ISAR motion compensation method based on the image entropy is presented. With the minimum entropy criterion, the motion compensation to the echo data is implemented by means of the optimum estimation to the radial motion parameter of the target through the iteration operation, and the two-dimensional high-resolution image of the target can be obtained. By sirnu latin, it is proved that this method is feasible.
