引言当以单脉冲雷达跟踪仰角大约小于一个波宽目标时,雷达系统“看见”目标及其影象并试图使分成信号为零。雷达或是在一中间位置振荡或是明显随机地在超越水平线大约一个波宽角度上振荡。在这些条件下雷达因此会丢失目标跟踪。多路径存在条件下单脉冲雷达性能分析除非方位和俯仰跟踪通道中存在交叉干扰,否则忽略方位跟踪误差这里只考虑俯仰通道跟踪误差。多路径存在条件下从传统的单脉冲雷达可得的Σ和△通道两倍信号是来自如图1
INTRODUCTION When monopulse radar is used to track elevation angles less than a wave-width target, the radar system “sees” the target and its image and attempts to zero the split signal. The radar oscillates either at an intermediate position or at a random, random angle about one horizontal wave width beyond the horizon. Under these conditions, the radar will lose its target tracking. Performance Analysis of Monopulse Radars in the Presence of Multipaths The azimuth tracking error is ignored here unless there is cross-interference in the azimuth and pitch tracking channels. Multiplicate existing conditions from the traditional monopulse radar sigma and △ channel twice the signal is from Figure 1
