Algorithm detecting the laser weak target with dynamic programming

To solve the laser weak echo detection under the clutter background, a dynamic programming (DP) technique has been developed for the detection of weak targets. The primary advantages of DP are its sensitivity to weak targets along with its robustness to laser echo glitter. DP technology turn searching track of the target into the subsection optimization of the target. First, DP algorithm finds all track subsection of target. Second, these track subsections are synthesized into the potential track of target. Third, the track of the same target is combined. Then the detection outcome is found. Theory analysis and the simulated results indicate a sensitivity improvement of detection performance over conventional detection algorithm. 2009 SPIE.
