准确获取光学测量中目标的角度是实现高精度的靶场光学测量的关键之一,而大气折射是影响最终计算目标角度的重要因素,需采用适当的方法计算得到目标的准确角度值.本文以分层处理为出发点,对影响大气折射率的主要因素气压、气温、湿度分别采用气压分层模型,气温分层模型,湿度分层模型,以大气折射率模型和接近靶场实际的大气实测数据为基础,根据斯涅耳折射定律和大气光路方程,建立了一种基于分层处理的光波大气折射精密修正方法.利用实际的星体观测实验数据对文中方法和常用的其它方法进行了比较,将处理得到的数据与星体真值进行比较;另外利用实际的靶场测量数据进行了对比处理,两种实验结果都能够说明本文中的分层处理方法可以实现更高精度的修正,可以最终提高光测设备的测量精度.

@@@@To accurately obtain the optical measurement of the angle of the target is one of the keys to achieve high-precision result in optical measurement applications. The atmospheric refraction is an important factor to affect the final calculation of the target angle, so appropriate method should be used to calculate the accurate angle of the target. Main factors affecting the atmospheric refractive index:pressure, temperature and humidity are processed separately with the hierarchical model, the temperature stratification model and humidity hierarchical model. Based on atmospheric refractive index model and actual measured data, according to Snell's law of refraction and atmospheric optical path equation, a precision correction method based on hierarchical processing of the light waves of atmospheric refraction is established. The method of this paper and other methods commonly used are compared with the data of stars observed. Additionally, the actual range measurement data is used to compare different methods. Results of both the experiments show that method of this paper can achieve more precise correction and ultimately improve the measurement accuracy of optical measurement equipments.
