Motion Compensation of Synthetic Aperture Sonar Based on Inertial Measuring System
基于惯性测量系统的合成孔径声呐运动补偿

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.
