宽波束雷达测高算法

Height-finding Algorithm of Wide Beam Radar

在弹载雷达平台不稳定的情况下,宽波束测高雷达比窄波束测高雷达更能使波束准确地指向雷达天底点。分别对回波前沿半功率点雷达测高算法、偏差重心雷达测高跟踪算法和平均高度雷达测高算法3种算法进行了仿真结果分析,通过对比发现平均高度测高算法测量精度最好。

In the condition that the platform of missile-borne radar is not stable,wide beam heightfinding radar can make the beam point at the radar nadir more exactly than narrow beam heightfinding radar.This paper analyzes the simulative results of three algorithms：radar height-finding algorithm based on echo front half-power point,radar height-finding tracking algorithm based on deviation of center of gravity and radar height-finding algorithm based on average height,discovers that the measurement precision of height-finding algorithm based on average height is the best through the comparison.
