逆合成孔径雷达相位补偿及优化成像

Phase Compensation and Optimal Imaging for Inverse Synthetic Aperture Radar

对逆合成孔径雷达成像中的相位补偿和小角度成像两个关键问题进行了讨论。提出了一种可望完全避免相位补偿的新方法——幅度谱成像法,并在理论上证明了其可行性.同时提出了用凸集合投影算法得到方位向超分辨的方法,并通过微波暗室实验证实了其有效性。

The two key problems in inverse synthetic aperture radar imaging; phase compensation and small - angle imaging are studied. A procedure called the magnitude-only imaging method is proposed and proved theoretically. This method is able to solve phase compensation problem completely. Further, a simple optimization method is proposed for obtaining super azimuth resolution. Efficiency of the proposed methods are supported either by computer simulation or by experiments.
