Abstract

The modeling and simulation of target laser scattering characteristic is one of the most important parts of the research of space object optical characteristics, and also is the basement of the design of active detecting system. LRCS is the integrated description of target laser scattering characteristic. In this paper, the BRDF model of space object surface materials, which is compatible with the active detecting geometry, is analyzed and selected, then a visualization method of calculating the LRCS based on OpenGL is put forward. Two 3D space object models composed of different materials are built and the LRCS values at different attitude angles and solar panel rotating angles are calculated. This method can increase the reliability and fidelity of the estimation of target LRCS. The maximum rang of active detecting system is also analyzed based on the estimation of LRCS. These research results of the LRCS can provide reference and foundation for the design of active detecting system.
