In the paper, remote target optical imaging simulation in space -based system was researched to provide the simulation data for space target recognition. An illumination model based on effective reflection area was proposed to solve the transformation among magnitude, gray and image point. Image authenticity was enhanced by adding Gaussian noise and background halo, and space object optical simulation image sequences were generated fi- nally. The experimental results show that the image sequences can reflect the movement change of space target and simulate the space - based optical imaging effectively, which can also supply the simulation data for space target recognition.
