Abstract:Considering the existing problems of information-aided tracking and reducing the amount of calculation of data association on the context of the complex environment of sea targets during the processing of multi-target tracking, a new way of data association based on the Amplitude Information(AI) of the signal is proposed. Firstly, the mathematic model of the signal amplitude is build. And then by bringing the signal amplitude into the traditional algorithm of Linear Joint Integrated Probabilistic Data Association(LJIPDA), a new linear tracking method of sea radar with AI aided data association is given. The simulation results show that the new LJIPDA-AI algorithm can effectively improve the tracking accuracy compared with the LJIPDA method, and reduce the computational complexity as well as improve the tracking accuracy compared with the JIPDA algorithm. In conclusion, the new LJIPDA-AI algorithm can effectively improve the tracking performance in complex sea environment.
