Because of higher angular resolution and data rate,Infrared photoelectric sensor can effectively suppress electromagnetic interference and improve the anti-interference ability,which can complement with radar information. This study proposes an nonlinear short-dimenson filter based on orbit restrain,which can locate the target and get precise tracking status,and therefore improve the tracking and detecting ability. This algorithm can significantly improve tracking precision and robustness. Lastly,simulation results show the feasibility and performance of the algorithm.
