摘要
针对光学测量系统测量得到的空中目标俯仰角数据,包含了大气折射带来的误差问题,建立了俯仰角修正误差模型,并详细介绍了修正模型具体计算实施过程,提出了采用三弯矩方程计算任意高度大气折射系数和高斯积分计算俯仰角折射修正值.经俯仰角折射效果分析和实践证明该方法精确、有效,满足高精度数据处理的要求.
According to the data of air target elevation angle measured by optical measuring system, which includes the error of atmospheric refraction, the model of elevation angle correction is built, the process of errorcorrection model computing is introduced. The calculation of atmospheric refraction coefficient with three bending moment equation and calculation of elevation angle refraction correction value with Gauss integral are proposed. The practice verifies that the method is precise and effective, which can be adapted to the demands of high precision data processing.
