为了实现精确打击的需要,越来越多的飞行器采用末段寻的制导技术。在寻的制导系统中,由于导引头、导引头罩的引入,给制导系统的设计带来了一定的复杂性与难度。本文以雷达末制导系统为应用背景,首先建立了雷达导引头模型,然后对整个寻的制导回路进行了建模,最后对制导回路的闭环及开环稳定性进行了仿真分析。所建模型与分析结果对飞行器寻的制导系统的设计具有重要的指导意义。
In order to achieve the precise blow needs more and more aircraft using the last section to find the guidance technology. Seeking guidance system, due to the introduction of seeker, seeker, introduced to the guidance system design has brought some complexity and difficulty. In this paper, the radar end guidance system is used as the background. Firstly, a radar seeker model is established, and then the entire guidance loop is modeled. Finally, the closed-loop and open-loop stability of the guidance loop are simulated. The model and analysis results have important guiding significance for the design of the guidance system of the aircraft.
