本文介绍了雷达制导低空防空导弹的实际设计依据。低空目标信号与大量的地面反射干扰信号以及大量的平静海面反射多路径信号混合,进入接收机。利用多卜勒效应与布鲁斯特角效应从地面反射干扰和海面多路径混杂中分离出真正的目标反射圆波。在这篇有关导弹制导和控制系统的文章中,讨论了探测器的一些设计因素。其中包括杂波以及路径仰制,多卜勒分辨和探测器稳定性。本文通过对一个脱靶量示例的定量分析讨论了脱靶量的主要影响因素,从而说明导弹横向加速度能力的作用。
This article introduces the actual design basis of radar-guided low-altitude air defense missiles. The low-altitude target signal is mixed with a large number of ground-reflected interfering signals and a large number of serene sea-surface reflected multipath signals into the receiver. Doppler effect and Brewster angle effect are used to separate the true target reflected circular wave from the ground reflection interference and the sea surface multipath mixture. In this article on missile guidance and control systems, some of the detector design considerations are discussed. Including clutter and path Yang, Doppler resolution and detector stability. In this paper, the main influencing factors of miss distance are discussed through the quantitative analysis of a miss distance example, so as to illustrate the function of missile lateral acceleration capability.
