Paper Abstract

In order to enhance the capability of space-based surveillance, the detailed non-resolved space object characterization with brightness data is described in this paper. Firstly, according to the optical scattering theory, mathematical model for brightness characteristics of space object is established with the bidirectional reflectance distribution function (BRDF) by region classification and grid division. Then, brightness of typical geosynchronous satellites is simulated. Influences of the shape, size and status on brightness are analyzed. Characterization with brightness data is proposed. It shows the shape, size and status of the object can be deduced with brightness data over a range of time-space periods. Finally, the several special fields of non-resolved space object characterization are discussed
