基于高分辨距离像的单脉冲角跟踪技术

 本文针对宽带毫米波雷达角跟踪中的角闪烁问题 ,提出了所谓基于高分辨距离像的单脉冲测角新算法 ,该算法根据单脉冲雷达原理 ,在测角之前首先对目标回波信号进行一维成像处理 ,然后以距离像作为单脉冲比幅信息 ,得到目标各距离单元的角度位置 ,经过一定的平滑处理 ,最后得到目标的径向几何中心的空间角度 .仿真实验表明该算法可以大大提高单脉冲雷达的角测量精度.

High Resolution Profile-based Angular Tracking Technology for Monopulse Radar

Designed for the glint of the wide band millimeter radar in angular tracking,a new angular algorithm is presented based on high resolution range profile.In this algorithm,the return signal is processed into one dimension profile prior to monopulse angular procedure,then we can get the angle series versus range cell.After smoothing process,we can obtain the position of the center in the target.The simulation test prove that this algorithm can greatly improve the angular accuracy.
