neighborhood correlation

In practice , it ’ s very hard to find any ideal scatter points to track , so this thesis focuses on the motion compensation algorithm base on motion parameters estimation , which is used in r - d fft imaging algorithm and verified by simulation . work of this thesis contains : first analyze the signal - processing model of isar system in detail , and establish a 3 - dimensional mathematical scattering model of moving target . then some improvements are made on existing compensation algorithm , to get a higher image quality and reduce compute burden
本论文有以下几点创新: 1 .在距离向的补偿(包络对齐)方面,采用基准相关法代替相邻相关法或积累相关法,一定程度上解决了可能出现的包络漂移和包络突跳现象;根据目标运动轨迹特点,采用二次曲线拟合的方法,将包络对齐时的局部误差转化为全局的误差,以便实现较优的整体对齐效果。
