摘要

以集中式融合结构雷达网为研究背景,从电子战飞机(ECAV)产生虚假航迹的原理出发,针对真/假航迹空间分布差异,提出了基于均值-方差联合检验的航迹欺骗干扰识别技术。首先分析了真/假航迹的统计特性差异,然后利用多个时刻航迹的坐标差,并通过坐标差的协方差阵对角化和归一化处理来构造检验样本,最后利用似然比统计检验的方法实现了虚假航迹的识别。仿真结果表明该技术能够对航迹欺骗干扰进行有效的识别,在雷达测距精度、测角精度变化的条件下仍能保持较高的识别率。

Abstract

Under the background of radar network with the centralized fusion architecture an algorithm for phantom track jamming recognition is proposed in the presence of the difference of spatial distribution property between phantom track and target track, which is based on the mean-covariance collaborative testing. The algorithm originates from the generation mechanism of phantom track by electronic combat air vehicles (ECAV). Firstly, the difference of the statistical property between the true track and phantom track is analyzed. Then, the multi-time coordinates difference is used to construct the testing sample set according to diagonalizing and normalizing of the coordinates difference covariance matrix. Finally, the phantom track is recognized by the mean-covariance collaborative likelihood ratio testing. The results of simulation show that the phantom track can be recognized effectively according to this technique, and the correct recognition rate is still high when the random range measurement error and angle measurement error change.
