Abstract:

In order to reduce the radiation risk of the sensor system during target tracking, the scheduling problem of active/passive sensors is studied. By establishing a sensor scheduling model based on the Partially Observable Markov Decision Process, the prediction formulas for target tracking accuracy and system radiation cost are given, the target function is established to meet the tracking accuracy constraint and the system radiation cost is minimized. An improved distributed auction algorithm is designed to solve the problem. Simulation experiments show that the method proposed in this paper can reduce the system radiation risk without sacrificing the tracking accuracy by reasonably scheduling the active/passive sensors on each platform.

Key words: sensor scheduling, target tracking, partially observable Markov decision process, radiation cost, auction algorithm
