激光制导炸弹弹目视线半实物仿真方法的研究

A Study on the Hardware - in - the - loop Method(Hwil) for the Line of Sight of Laser Guided Bomb(Lgb)

针对风标式导引头测量轴线随遇稳定到制导炸弹相对速度方向上的特点，提出采用等效弹目视线半实物仿真方法来解决三轴飞行转台无法模拟风标式导引头测量轴线角运动的问题。给出等效弹目视线空间方位的计算方法，讨论并分析了影响等效弹目视线仿真精度的因素。

Due to the scale axis of weather cock seeker dynamically stabilizing to the relative velocity Of LGB, this paper puts forward the HWIL method using the equivalent line of sight(ELS) to solve the problem that three -- axes flight bench can't simulate the angular motion of the scale axis of weather cock seeker. Gives out the calculating method on the spatial position of ELS, discusses and analyzes the factors affecting on the accuracy of ELS.
