| 摘 要： | 目标的角闪烁在近距离对跟踪雷达产生严重的影响,不能有效抑制角闪烁将有可能导致角跟踪失败。研究了2种抑制角闪烁的方法,即利用RCS和角闪烁之间的相关性抑制角闪烁方法及利用过门限相参信号各点计算角误差并使用这些角误差的均值解算角误差的方法。通过实采近距离大型渔船数据对比了2种方法,实验结果表明使用过门限相参信号各点计算角误差并使用这些角误差的均值解算角误差可更好地抑制角闪烁。

| Abstract: | The angular glint of targets has high effect for radar tracking,ineffective suppression of angular glint will induce failure in angle tracking.Two methods of suppression of angular glint are stu-died,using the pertinence between RCS and angular glint to suppress angular glint and the method of using threshold crossing coherent signal to reckon angle error and the angle error average to reckon angle error.Contrast the two methods through sampling the data of close quarter large hooker.The result indicates using this method can suppress angular glint better. |
