摘要
模板匹配方法是一种常用的一维距离像识别方法。针对该方法应用中的姿态敏感性问题,提出了自适应姿态角域平均一维距离像模板建立的方法。通过理论分析证明平均一维距离像具有良好的稳健性。姿态角域平均一维距离像相关性分析表明自适应姿态角域平均一维距离像可以表征目标不同姿态下的一维距离像。利用实测数据,通过仿真测试表明自适应姿态角域平均一维距离像模板建立方法是可行的。
Template matching is a common method to identify the one-dimensional high-resolution range profile （HRRP）. In view of attitude sensitivity in the application of the method, a method of creating the adaptive attitude angular-domain average 1 D HRRP templates is proposed. The average 1 D HRRP features good robustness through theoretical analysis and verification. The relevant analysis on the attitude angular-domain average 1 D HRRP indicates that it can represent 1 D range profiles of the targets with different attitudes. The test data and simulation results show that the method above is feasible.
