| Abstract: | The model of complex object is built by use of 3DMAX, obtaining data file of 3ds style. The fly-1 satellite model is constructed and its surface is consistent of triangular facets and grid generation. The light scattering of typical objects and fly-1 satellite model are calculated with Kirchboff approximate theory. The characteristic information of scattering depends on the shape of objects. The scattering character of fly-1 satellite is related to different material parameters and the relation of them is drawn. |
