An improved MTI algorithm is proposed in this paper to solve the problem of space objects detection in video satellite images. In order to detect the inconsecutive target's trajectory, at the beginning of the algorithm we set a special preprocessing which is called pixel's feeling domain. To reduce the time of the algorithm, we simplified the time projection part of the classic MTI algorithm, which is used to restrain the background. Finally, targets trajectories are obtained through connected domain detection. The experimental results show that, the improved MTI algorithm can effectively eliminate the background and is suitable for the inconsecutive target's trajectory detection. In addition, the algorithm's processing speed almost meets the real-time task.
