New Track Correlation Algorithm of Distributed Multi-sensor System

In multi-target and false alarm scenario, the effect of the traditional optimal track correlation algorithm based on statistics of two local nodes canpsilat satisfy the need of engineering. A new global optimal track correlation algorithm based on the traditional optimal algorithms is presented in this paper. The new algorithm eliminates some false tracks from the optimal assignment process according to an adaptive threshold method. Simulation result shows that the adaptive threshold algorithm can improve the correct correlation probability by 5~9 percents, and the run time of the new algorithm is decreased compared with the former algorithm, so the new algorithm is effective.
