基于位置信息的高分辨雷达角闪烁抑制方法

角闪烁误差是导引头寻的制导的主要误差来源,基于高分辨力雷达的单脉冲测角算法可有效改善角闪烁现象。现有的研究大多基于幅度加权的思想,利用距离单元的幅度信息进行加权平滑处理。本文在现有高分辨测角算法的基础上,结合高分辨一维距离像的位置信息,提出了一种新的角度信息处理方法。该算法充分利用了距离像有效单元的目标信息,提高了角度测量精度。仿真实验表明该算法对角闪烁有较好的抑制作用。

High Resolution Radar Angular Glint Suppressing Method Based on Location Information

The angular glint error is the main error of seeker homing guidance source. High resolution radar mono-pulse an.gle measurement algorithm can effectively improve the angular glint. Existing research is mostly based on the idea of ampli.tude weighting, weighted smoothly with amplitude information in distance unit. Based on the existing high resolution anglemeasurement algorithm, combined with the location information of high resolution range profile, in this paper, a new angleinformation processing method was presented. The algorithm made full use of target information in the effective unit ofrange profile, and improved the precision of angle measurement. The simulation experiment showed that the algorithm hadbetter inhibition effect of angular glint.
