运动补偿是提高ISAR分辨率的关键技术.本文从距离-多普勒成像原理出发,对几种典型运动误差的补偿问题作了有益的探讨,并给出了相应的光学补偿方案和实验室处理系统,获得了较好的实验结果.同时,讨论了一般运动误差的补偿方案及实时处理的可行性.
Motion compensation is the key technology to improve the resolution of ISAR.Based on the principle of distance-Doppler imaging, some typical compensation problems of motion errors are discussed in this paper, and corresponding optical compensation schemes and laboratory processing System, the better experimental results are obtained.At the same time, the compensation scheme of general motion error and the feasibility of real-time processing are discussed.
