舰船目标一维距离像多姿态角相关匹配识别

摘要

为提高高分辨雷达目标识别率,对多姿态角舰船目标一维距离像的相关匹配识别方法进行了研究。提出了一种以相关匹配法为基础,求取目标各姿态角一维距离像与模板之间的最大滑动相关系数,并与识别率建立对应联系,通过引入联合概率计算提高目标识别率的方法。这种方法较为贴近实际应用,在一定程度上提高了识别率,为目标识别提供了一条较为有效地途径。%The paper aims to improve the recognition rate of high resolution radar.The author proposed a method which is based on correlation matching algorithm.The method calculate the maximum sliding correlation coefficient（MSCC） between multi-aspect range profile and template.Then it established a link between the recognition rate and the MSCC and increase the recognition rate by calculate the joint probability the recognition rate of different aspect angles.It is applicable and practical.
