激光制导武器半实物仿真系统的设计与实现

首先，以某激光制导弹药为背景，提出了室内半实物仿真系统的总体设计方案，介绍了一种激光半主动导引头的工作原理。其次，在室内局限环境下，建立了弹目几何关系的数学模型，研究了导引头入瞳光学特性，并根据制导与控制系统的工作原理，设计了末制导段弹道的半实物仿真模型。最后，设置两种末端制导的初始条件，引入导引头和角速率陀螺等弹上部件进行多次弹道仿真试验。试验结果表明，基于该导引头和角速率陀螺的制导与控制系统设计合理，可以实现精确打击。

Design and achievement of hardware-in-the-loop simulation system for guided shell based on laser semi-active seeker

With background of terminal guided weapon, at first, a scheme of hardware-in-the-loop simulation(HILS) was derived; and the principle of laser semi-active seeker was introduced in detail. Secondly, in the limited indoor environment, mathematical model of geometry between missile and target was established; subsequently the optical characteristics of the laser received by seeker were researched; the model of HILS in the terminal trajectory was designed for guidance and control system. In the end, seeker and gyro was introduced into the closed loop of simulation, simulations were repeated many times under two different conditions of the initial state. In conclusion, the results indicate that guidance and control system of the missile based on this seeker and gyro is achieved correctly and have the ability to hit the target precisely.
