Dynamic Programming Ring for Point Target Detection

To improve the detection efficiency of a long-distance dim point target based on dynamic programming (DP), this paper proposes multi-frame algorithm merit function filtering DP ring (MFF-DPR). First, to reduce influence noise pixel state estimation results, second-order named MFF-DP is proposed. The current states pixels an image plane are estimated by maximizing addition functions previous two frames and observation data frame. In addition, suppress diffusion function, sequential reverse connected in head-to-tail manner form structure. applied structure, MFF-DPR obtained averaging MFF-DPs. Finally, trajectory correlating extreme points MFF-DPR. simulation analysis results show that merely adding probability traditional can be improved up 40% when detecting targets under SNR 1.8. achieve significantly better performance compared with DPs or without proposed suitable for radars infrared systems.
