Non-myopic Scheduling Algorithm of Multi-platform Active/passive Sensors for Collaboration Tracking

A non-myopic scheduling algorithm of multi-platform active/passive sensors for collaboration tracking is proposed in order to track the maneuvering target in clutter and reduce the system emission risk. The non-myopic scheduling problem is formulated as a partially observable Markov decision process. The target belief state is updated by using the interactive multi-model and the probability data association algorithm, and the posterior Carmér-Rao lower bound is utilized to predict the non-myopic maneuvering target track accuracy. An improved Viterbi algorithm is proposed to search the optimal scheduling sequence. Simulated results show that the proposed search algorithm can be used to reduce the searching space and memory space, control the system emission cost and reduce the excessive sensor switching effectively.
