在外场用已知半球反射率的靶板作为标准靶板，反演测定目标靶板激光雷达散射截面和半球反射率。

Using a plate whose hemisphere reflectivity is known as a standard plate, the lidar scattering cross section (LRCS) and hemisphere reflectivity of a target plate are measured inversely.

在利用漫反射板标定光谱辐亮度的实验装置中，标准灯完全可以近似为点光源。

For experimental setup to calibrate spectral radiance by applying a diffuse plane, the measured spectral radiance can be obtained through integral of spectral radiation flux entering the spectrometer.
