Abstract: A new algorithm combined facet model and prediction method is presented to detect infrared small moving target in image sequence.Based on the moving continuity and direction of the target in image sequence，a second-order auto-regressive prediction model of the target search window is developed first；The authors then research the method of fitting the image intensity surface of the search window by cubic facet model，and exploite the detect operators to search maximum intensity points in the window.The possible small target position is determined by the maximum intensity points according to the intensity feature of the target in infrared image.Experimental results with the infrared image sequence show that the proposed algorithm can successfully detect the small target，the real-time and anti-noise performance of the algorithm are better than traditional algorithm.
