摘要
介绍了基于Matlab/Simulink的反鱼雷鱼雷固定提前角导引弹道的仿真方法。根据固定提前角导引规律,给出了反鱼雷鱼雷导引系统的数学模型,采用Simulink建立系统的仿真模型并进行仿真计算。仿真结果表明基于固定提前角导引法的反鱼雷鱼雷自导系统具有较高的追踪效率;提高反鱼雷鱼雷速度能缩短自导时间;根据来袭鱼雷方位选取合适的提前角和发射角能够有效提高拦截效率。
In this paper, a simulation method of fixed lead angle guidance （FLAG） trajectories of anti-torpedo torpedo was mainly intro- duced based on Matlab/Simulink. Based on the law of FLAG, the mathematical model of anti-torpedo torpedo guidance system was discussed. Then, the simulation model was designed with Simnlink. Simulation shows that the intercepting trajectories of anti-torpedo torpedo based on FLAG has a higher interception probability, and increasing the velocity of anti-torpedo torpedo can reduce guidance time. Choosing appropriate fixed angle and launch angle can enhance the interception probability effectively.
