| 摘 要： | 本文针对高距离分辨雷达体制与地面坦克目标识别应用背景,提出了一种基于自适应相关匹配的雷达目标距离剖面像识别的新方法.这种方法根据给定的误判概率与拒判概率的要求,设计和得到目标姿态角的一种区域划分,确定相关匹配分类器的数目,并按最优化准则构造匹配分类器;根据实测距离剖面像的长度来选择相应的分类器进行匹配识别,以适应目标不同的姿态角;具有匹配运算量少,所需匹配滤波器数目少等优点,为解决地面背景中坦克目标的识别提供了一条有效途径.

| Abstract: | In this paper, a novel method of land tank target recognition for high resolution radar is presented by using adaptive matched-filtering of range profile. In the method, the given probability of misjudgement and rejection is used to obtain a region segmentation of target angles and to decide the number of the matched-filters which are constructed according to the criterion of optimization. And the received range profile can be recognized according to its radial length by choosing appropriate filters for matched processing. The method has the advantages of adaption to variation of target angles, little capacity of computation and few numbers of matched-filters, and is helpful for tank target recognition under land clutter background. |
