| Abstract: | Visible reflection characteristics of an on-orbit satellite were studied based on background radiation,surface material properties,orbit parameters,and the relative motion between satellite body and solar array.The Bidirectional Reflectance Distribution Functions(BRDF) of three common surface materials of satellite at typical angles were measured.An improved Sun BRDF model of three materials was established.The method for calculating the incident vector in the coordinate system of solar array with a single ... |
