An Integrative Processing Algorithm of Passive Detection and Tracking

An integrative algorithm of passive detection and tracking of underwater moving target based on the co-processing algorithm of matched-field and long time integration is proposed. The probabilistic data association technique is introduced into the co-processing algorithm. First constitute the test statistic and then calculate the posterior data association probability to establish the information fed back from the tracker to the detector. On the process of detecting and tracking, the single model method and the multiple models method are used to simulate the moving state of the target. The integrative algorithm is proved effective by the data from the experiment on the sea
