A new multiple targets tracking algorithm based on improved MHT algorithm

Abstract

In this paper, a bearing pretreatment method suitable for passive sonar tracking is proposed, when the ocean background noise fluctuation is large, the weak target can also be detected and tracked through the adaptive adjustment of the threshold. The principle and characteristics of the conventional multi-hypothesis tracking algorithm is explored in this paper, we propose a bearing information pre-processing method suitable for passive sonar tracing and an improved MHT method based on Kalman prediction framework. Finally, automatic tracking problem with multi-targets based on bearing crossing and ocean background fluctuations can be achieved. The simulation data proves that this method is reliable and practical.
