为了实现激光模拟训练系统的弹道模拟，以双光楔光束偏转性质为基础，研究了通过控制双光楔的旋转角度来控制激光光轴的偏转，并根据光折射理论计算推导了双光楔角度控制方程。结果表明，模拟训练系统激光光束指向精度高于1mrad,能够满足实际需要。该系统可用于坦克等直瞄重**的实兵对抗训练。

In order to actualize ballistic trajectory simulation in a laser simulation training system, on the basis of the beam deflexion character of dual-wedge, the laser beam was deflected by control turning angle of the dual-wedge. The formula for controlling the turning angle of dual-wedge was also deduced from the optical ray refraction theorem. The experimental results indicate that the laser beam pointing accuracy of the system is higher than 1mrad. This system can be used for force-on-force engagement training of direct heavy weapons such as tanks.
