A Moving Target Tracking Method for Airborne Wide Area Surveillance Systems

Wide Area Surveillance Ground Moving Target Indication mode is an important mode in surveillance radar systems since it can monitor extensive area in a short time, which enables moving target tracking. A method for tracking ground moving targets based on airborne wide-area surveillance radar system is proposed in this paper. First, the location of the moving targets is estimate according to the moving target information obtained from the detection process. Then a correlation threshold is selected for each target to decide which one would compute weighted relate-rate. Finally, the global optimal relevance is computed. This paper analyzes the applicable error scope of the method. The algorithm is compared with another two methods in the simulation and proved to be effective. Moreover real data results demonstrate the feasibility of the proposed method
