【Abstract】In consideration of the radiation control for target detection and tracking, a non-myopic scheduling algorithm for multi-sensor collaborative detection and tracking is proposed. Firstly, the model of target tracking and radiation control is formulated as a partially observable Markov decision process (POMDP). Then, the detection probability of the new target is calculated by the randomly distributed particles; the non-myopic tracking accuracy is predicted by the posterior Carmér-Rao lower bound (PCRLB); the non-myopic radiation cost is derived by the hidden Markov model (HMM) filter. Finally, the non-myopic optimization function of radiation control constrained by the detection probability of the new target and the tracking accuracy of the existing target is set up. The optimal scheduling sequence is obtained by the branch and bound algorithm based on a greedy search. Simulation results verify the effectiveness of the proposed algorithm.
