The Simulation of Attack Area for Air-to-air Missile Based on Matlab/Simulink

针对导弹攻击区仿真计算中存在的可视化效果差、编程复杂、计算时间长问题,提供了一种简便有效的方法。首先,利用Matlab环境下的Simulink工具箱,基于模块化的设计思想建立了弹道仿真模型;然后,建立了脚本文件,运用Matlab语言编程,设置仿真参数,改变目标进入角,采用二分法计算弹目初始距离,并在脚本文件中调用Simulink弹道仿真模型,计算空空导弹攻击区;最后,通过仿真验证了弹道仿真模型的正确性和攻击区计算方法的可行性。

Aiming at the problems in simulating and calculating attack area of air-to-air missile,a simple and convenient method for simulating and calculating attack area of air-to-air missile was provided.Firstly,missile trajectory simulation model was established according to modular design method,including target motion module,missile motion module,relative motion module,missile guidance module and hitting conditions restriction module;Secondly,a script file was established and Matlab programme was used for setting simulation parameters,changing approaching angle and calculating the distance between missile and target according to dichotomy,then missile trajectory simulation model was transferred.Lastly,the correctness of the missile trajectory simulation model and the feasibility of the calculation of attack area were proved through simulation.
