Scattering modeling of space objects based on Kirchhoff approximation

摘要

To improve the capabilities of detection and identification of space object, the need for spatial modeling of object scattering properties. In this paper, the scattering properties of space objects were studied by the Kirchhoff approximation theory. The radiance of surface element was calculated. And then the radiance model of the space objects and the solar panel was built combined with the geometry of the objects. Therefore, the radiance of the space objects in the visible arc area was observed according to the proposed model. According to the analysis of the simulation result, the method not only can describe observational irradiance characteristics of space object efficiently, but also offer the data for the research of observation system.
