In order to enhance the capability of space-based surveillance, the detailed modeling for visible imaging characteristics of space object is described in this paper. Firstly, a space-based imaging detection model is built based on the scattering visible radiation from space object. The model consists of radiation transmission based on the bidirectional reflectance distribution function (BRDF) and grayscale transformation based on the 256 levels. Then, according to the position of the sun, object and detector, the imaging conditions such as imaging angle and size are analyzed. Finally, the grayscale images of the HuanJing-1 satellite are simulated. It shows the grayscales for the different regions of the object appear great difference, indicating that the space-based detector needs a larger dynamic range.
