Abstract :
The spectral bi-directional reflectance distribution function (BRDF) of some satellite coating material and solar plane samples in the band from 380 to 780 nanometres is measured with relative measurement in the laboratory. The spectrum BRDF which can characterize the spectrum reflectance property of samples is obtained by weighting the measured spectral BRDF by the spectral irradiance of the incident spectrum. A new method to calculate the visible light scattering of spatial object is introduced with the aid of the spectrum BRDF. As an application example, the visible light scattering of a simple satellite model is calculated.
