便携式地空导弹超前修正导引弹道模型的仿真研究

Trajectory Simulation of Proportional Navigation Guidance Law for Leading Impact Point of Portable Ground-to-Air Missile

红外被动寻的便携式地空导弹，为命中目标实体必须引入前向偏移装置，对导弹控制弹道进行修正，提高命中率。本文用MATLAB／Simulink语言建立并分析了由前向偏移装置引出的超前修正导引弹道模型，最后给出了得出此模型能使导弹弹道倾角和视线角速度发生变化，从而实现导弹弹道前向偏移而命中目标实体的结论。

In order to improve the accuracy of shooting target＇s entity for infrared passive homing guidance of portable ground-to-air missile, it should build a front equipment to be partially to move,and revise the missile trajectory. The paper establishes and analyzes the modeling for proportional navigation guidance law for leading impact point according to the front equipment to be partially to move based on the MATLAB/Simulink toolbox, and make the conclusion that the change the missile＇s trajectory slope angle and front-to-moving of missile trajectory and shoot angular target＇s speed of LOS （line of sight）, entity. regulation could then realize the
