激光制导武器反射式弹目视线半实物仿真方法研究

Research on the Method of Light of Sight Simulation in Reflective Target Simulating

本文从弹道仿真视线角模拟的角度,推导光斑位置与弹目视线的关系。针对空地武器飞行弹道基本以负视线角为主,靶面面积有限无法实现大范围负向视线角范围模拟的问题,通过坐标转换的方法,将试验系统的基准坐标进行调整,利用三轴飞行转台正向运动空间大的特点,将仿真模型中的惯性坐标系零位调整到实际惯性空间的某一角度上,拓展转台负向俯仰运动空间。最后给出光斑位置的解析表达式,同时给出三轴飞行转台驱动角度的计算方法。

From the perspective of light of sight simulation,this paper infered the relationship between the position ofligh spot on reflection screen and the angle of LOS.Due to the LOS of air-to-ground weapon is always minus,reflection screen with flight turntable hight cannot simulate the wide scale LOS.Using coordinate transforming to adjust thebase coordinate system,we can set some appropriate orientation in inertial space as the original position of the turntable.In this approach,the scale of LOS simulation can be expanded to meet the LOS requirement of trajectory simulation.Finally,analysed expression of the vector of light spot position is obtained.
