文中导出了激光测距数据水平折射率梯度效应的修正公式。该公式需要激光位置上的水平压力和温度梯度值。为评价该方法的精度,将公式与用射线跟踪法计算的距离修正作了比较。
In this paper, the correction formula of the horizontal refractive index gradient effect of laser ranging data is derived. The formula requires horizontal pressure and temperature gradients at the laser position. To evaluate the accuracy of the method, the formula was compared with the distance correction calculated by ray tracing.
