摘要
光学雷达是靶场试验外弹道测量系统中的主要设备之一。由于大气对光波传播引起的折射效应,使得光学雷达测量中产生折射误差。针对靶场常用的光学雷达系统,根据光波射线在大气中的运行轨迹,利用逐次逼近法得到了实用的光学雷达大气折射误差修正方法。通过对某靶场的实际测量数据检验,证实了该方法的适用性和有效性。目前,该方法已成功地应用于试验靶场,满足了靶场试验的精度要求。
The optical radar is one of the main equipments in shooting range test outside measurement system. The refraction effect of light-wave when it propagates in atmosphere brings error to optic radar＇s measurement. Aimed at the optical radar system that commonly used by trajectory refraction shooting range, based to the light-wave radial＇s operation trajectory in atmosphere, and using the method of successive approximation, we obtained an applied atmospheric refraction error correction method of optical radar. Tested by the actual metrical dates of a shooting range, the applicability and validity of this method was proved. At present, this method has been applied in test shooting range successfully, which satisfied the precision request of shooting range testing.
