A Dynamic Sensor Allocation Algorithm for Collaborative Tracking in Asynchronous Radar Networks

A dynamic sensor allocation algorithm based on the sequential asynchronous fusion for collaborative tracking system in the asynchronous radar networks is proposed. The algorithm estimates the target states with the sequential filtering fusion of asynchronous sampling measurements and selects the optimal sensor sets based on the difference between the expected covariance and the filtering covariance dynamically. Simulation analysis show that the proposed algorithm has lower computational load and higher target tracking accuracy compared with the dynamic sensor allocation algorithm based on pseudo-measurements.
