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
本論文有以下幾點創新: 1 .在距離向的補償(包絡對齊)方面,採用基準相關法代替相鄰相關法或積累相關法,一定程度上解決了可能出現的包絡漂移和包絡突跳現象;根據目標運動軌跡特點,採用二次曲線擬合的方法,將包絡對齊時的局部誤差轉化為全局的誤差,以便實現較優的整體對齊效果。
