摘要
本文构建了数字变极化单脉冲探测系统,该系统采用多种发射极化形式,利用虚拟极化合成接收,对地面目标进行探测实验,得到全极化高分辨一维距离像,获得散射熵H和平均散射角α在距离像中的分布,联合距离高分辨和目标极化散射特性为目标可靠检测和准确识别提供依据,表明了目标极化散射熵在数字变极化探测系统中对地面目标的检测和识别的可用性.
This paper constructs a digital variable polarization monopulse detection system,which uses variety of emission polarization and virtual polarization synthesis receive mode,and obtains the full-polarimetric HRRP and scattering entropy H and average scattering angleαby the ground target detection,provides the basis for reliable target detection and accurate recognition by combining HRRP and target polarimetric scattering characteristics,and illustrates that target scattering entropy can be used in the ground target detection in the digital variable polarization detection system.
