摘要
大气折射是影响目标外弹道参数光学测量的重要因素之一,当对测量精度要求较高时,需对光学测量设备的折射误差进行修正。针对标准方法理论推导过程不够精确,计算过程中需要反复迭代的问题,根据光学测量设备的特点,以大气球面分层模型为基础,提出了基于测角交汇的大气折射修正方法。进行了仿真模拟和无人机飞行实验,结果表明,相比标准方法,该方法计算速度更快、修正精度更高。
Atmospheric refraction is one of the important factors affecting the optical measurement of the target''s external trajectory parameters.Atmospheric refraction correction is necessary under the condition of higher measurement accuracy for optical equipment.aiming at the problem that the theoretical derivation process of standard method is not precise enough and repeated iterations are needed in the calculation process,based on atmospheric sphere sublayer and optical equipment features,an atmospheric refraction correction method based on angular intersection is proposed.Simulations and unmanned aerial vehicle flight test show that proposed method is faster and more accurate than the standard method.
