摘　　要：本文采用一维距离像相关模型,提出一种ISAR成像中距离对准的新方法,该方法充分考虑了一维距离像间的直流漂移和归一化系数,且具有较好的对准效果,通过实测数据验证了该方法的有效性。In this paper,based on coherent model of range profiles,a new algorithm for alignment of range profile is presented. DC excursion and normalization coefficients are under consideration in this method, so good alignment result is obtained. The efficiency of this new algorithm is demonstrated by experiment based on real data.
