| 摘 要： | 运动补偿是实现高分辨率合成孔径声呐(SAS)成像的关键问题之一，该文研究了基于惯性测量系统的合成孔径声呐运动补偿过程。提出了一种改进的基于实际航迹的逐点补偿成像算法，该算法解决了传统的逐点延时相加成像算法不能直接应用测量数据进行运动补偿的问题。最后，通过仿真和湖试实验，验证了算法的有效性。

| Abstract: | Motion compensation is very important for high resolution SAS image. In this paper , the process of motion compensation based on inertial measuring system is discussed in detail, and then an improved point-by-point compensate image algorithm based on actual azimuth track is presented, which solves the problem that the traditional point-by-point image algorithm can’t use directly for motion compensation. At last, simulation and lake experiment results confirm the efficiency of the algorithm. |
