末制导雷达捕捉目标所需角度搜索范围研究

Research on Searching Angle Rangeof Terminal Guidance Radar to Capture the Target

摘要:

为了减少反舰导弹受冲淡干扰的几率,要求末制导雷达在保证捕捉概率的同时尽量减小角度搜索范围。为此,提出了末制导雷达捕捉目标所需最小角度搜索范围模型,推导了最小角度搜索范围表达式及其对应的最佳开机距离表达式。在不同的探测距离下,以高亚声速反舰导弹为例进行了仿真计算。结果表明,最小角度搜索范围在?30?之内,小于某些反舰导弹的角度搜索范围。

Abstract:

In order to reduce the chance to be disturbed by dilution jamming, the terminal guidance radar of anti-ship missile should reliably capture the target with minimal searching angle. A model of the minimal searching angle to make sure the terminal guidance radar reliably capture the target was introduced. A minimal searching angle model was established by means of an analytic algorithm, and its corresponding optimal working distance of terminal guidance radar was acquired. Simulation computations were taken based on high subsonic speed anti-ship missile with different detecting distances of terminal guidance radar. The minimal searching angle was found to be in the range between -30? and +30?, which was smaller than the searching angle adopted by some anti-ship missiles.
