The detection,recognition and tracking ofpoint targets are the key technology to enhance the ability of guidance dissertation studied the moving point target detection algorithm under the condition of low signal··to-·noise.-ratio(SNR)for the requirement of the national high technology 863,and developed a dynamic programming(DP)and track matching were achieved by performing directional weight operation precede to DP and target data association.
In this dissertation,paring and analyzing several primary moving point target detection algorithms,the DP algorithm was selected and
improved DP algorithm has merits of simple and high efficiency,enhanced the probability of of the aJgorithm was theoretically the same time how to select parameters of the algorithm was , computer simulations weFe done and the implementation performance of the
algorithm on hardware Was analysis and simulations indicate that the algorithm has good performance of detecting moving point target which range
of the target speeds was known.
Keywords:
point target detection,dynamic programming,Track matching Prediction
