Lambert's cosine law

Sprayed BaSO 4 diffuser plate is the most Lambertian surface actually used in spectral radiance calibration known by now.

通过实验测量硫酸钡漫反射板 2 5 0～ 4 0 0nm的半球反射率和双向反射分布函数表明 ,实测的双向反射分布函数与假定漫反射板为朗伯表面根据测量的半球反射率计算的双向反射分布函数的相对差值为 6 7% ,实测的双向反射分布函数随散射角的变化可达 2 8%。

The soil with relatively high moisture was represented as Non Lambert reflector,while the soil with low moisture was represented as Lambert reflector.

多角度遥感中我们发现具有一定湿度的土壤表现为非朗伯体。

The concept of Lambert reflector used in the phenomenon of optical diffuse scattering and the analytical method were introduced.

将描述光学漫散射现象的朗伯体概念和分析方法应用在兵器目标的雷达散射截面积计算上,通过对朗伯表面的散射强度计算和实例模拟分析,提出了利用散射-吸收型材料构造朗伯表面实现地面兵器目标雷达波隐身的一条新途径。
