基于复杂度分析的自动目标识别方法

Method of ATR Based on Complexity Analysis

雷达目标的高分辨率距离像反映了目标的散射中心在径向的分布,该分布与目标的几何外形密切相关。文中将一帧距离像看作一个序列,用提出的一种新的算法对该序列进行预处理,然后求出预处理序列的Lempel-Ziv复杂度,将其用于目标识别。试验结果证明了该识别方法的有效性。

High range resolution profiles （ HRRPs ） give the distribution of the scatterers of radar targets along the radial dimension, which is closely related to the target geometry. In this paper, an HRRP ,seen as a series, is pre -processed by using a newly introduced algorithm, then the Lempel-Ziv complexity of the preroeessed series is calculated and is used for target recognition. The experimental results demonstrate its effectiveness.
