摘要：
The detect and track of the weak target in Bearing-Time Record (BTR) was studied in this paper. The distribution of the measurements of the BTR was derived. And a method of track before detect algorithm based on Hidden Markov Model was given. The simulation and the experiment with real acoustic data showed the effectiveness of this method. The performance of the two classic algorithms Viterbi and Forward-Backward to solve this problem was also compared.
