摘要
针对高分辨导引头雷达在近距离跟踪目标时出现角闪烁问题,采用基于角闪烁抑制的高分辨测角算法。对回波信号进行一维成像处理,以距离像幅度作为单脉冲测角幅度,利用单脉冲测角方法得到目标在各个距离单元内的角度信息,通过加权平均处理,得到目标几何中心空间角度。仿真结果表明,该方法可以抑制角闪烁偏差,提高导引头角跟踪精度。
A new algorithm designed for the glint of the high resolution radar in near tracking is presented based on glint suppression.The return signal is processed into a one dimension profile,which has the range profile amplitude as the amplitude of the monopulse angular procedure;then we obtain the target＇s angular information within various range cells by the monopulse angular procedure;finally by the weighted average process,we obtain the position of the center in the target.The simulation result shows that this method can suppress glint and improve the angle tracking accuracy.
