基于灰关联分析的双通道雷达目标距离像研究

针对高分辨雷达在目标成像过程中存在的目标散射点越距离走动问题,利用双通道探测的有利条件对各通道散射点回波信号进行数学建模,根据双通道接收到回波信号的包络走动,引入了灰关联分析方法来研究回波信号包络间的关联度,根据分析结果分配各距离单元对目标距离像的影响权值,结果表明该方法可以有效地降低发生越距离走动散射点的影响。

Range Profile Research of Dual-channel Radar Target Based on Grey Associatlon Analysis

In order to solve problems related to target scatters radial shift during high-resolution radar target imaging,the advantages of dual-channel detection are taken to establish a scatters echo signals' math model.According to the variation of echo envelope,a grey association analysis is made to obtain the models' association law.The analysis results are used to determine the impact weights of unit distance to target range profile.The effect caused by scatters shift can be reduced effectively.Experiment results show that the method is practical.
