Target tracking technology for reducing false alarm

Because of the complex marine environment, there are a large number of false arms when the active sonar is detecting targets. It is difficult to find the real targets, so the false negative rate has a significant increase. In order to suppress the clutter better and reduce the false alarm rate maximally, the problem of target detection via Multiple Hypothesis Tracking based Track Before Detect (MHT -TBD) is considered in this paper. MHT -TBD is a data association method that could remove wild spots in a clutter environment and save useful data. But for high maneuvering targets, the tracking success rate of MHT-TBD is significantly reduced. An improved MHT-TBD method named interactive multimode MHT-TBD (IMM-MHT-TBD), which combines interactive multimode with multi hypothesis tracking is introduced in this paper. It shows a superior performance in high maneuvering targets tracking by maintenance and data association in a clutter environment. Simulation results show that IMM-MHT-TBD can solve the problem of ...
