摘要
雷达多极化组合态距离像与单极化组合态距离像相比包含了更多的目标信息,因此也具有更强的目标鉴别能力;而距离像不同的特征同样包含了具有一定差异的鉴别信息,可以用来提高距离像的总体识别能力。基于D-S证据理论将多极化信息和六种常用的距离像特征信息有效融合起来,获得了较高的识别率,基于仿真数据的实验验证了结论的正确性。
Radar multiple polarization high resolution range profile（HRRP） contains much more target information than single polarization range profile does, so it has stronger target identification ability too; Different features of range profile contains different identification information, so it can be used together to improve HRRP＇s recognition performance. Based on the Dempster-Shafer theory, the multiple polarization data and multiple features are fused efficiently to get a better recognition performance. Experiment results based on simulated data testifies the efficiency of this method.
