Abstract:

For the task of ground target detection and tracking task, a sensor scheduling method considering the blind zone is proposed with a multi-mobile-sensor system as the scheduling object. Firstly, a target detection model is developed and a calculation method of the target detection loss is given to evaluate the detection performance based on Bayesian risk theory. Then, a target tracking model is established considering the effects of Doppler blind zone and visual blind zone, and a target tracking algorithm based on blind zone information assistance is given to achieve the target state estimation when blind zones appear. Finally, a sensor optimal scheduling model is established, and the object optimization function is built combined with the detection loss, tracking accuracy, and sensor energy consumption. The simulation results show that the proposed scheduling method can effectively solve the multiple mobile sensors cooperative scheduling problem, and the corresponding optimal scheduling scheme can optimize the overall operational gain while balancing the detecting loss, tracking accuracy, and energy consumption.

Key words: sensor scheduling, mobile sensor system, target detection, target tracking, Doppler blind zone, visual blind zone
