摘　　要：为了降低目标跟踪时传感器系统的辐射风险,研究了主/被动传感器的调度问题。通过建立基于部分可观马尔可夫决策过程的传感器调度模型,给出了目标跟踪精度和系统辐射代价的预测公式,并以满足跟踪精度约束的同时系统辐射代价达到最小为优化目标建立了目标函数,设计了一种改进分布式拍卖算法以求解该问题。仿真实验表明,该方法能够通过合理切换各平台上的主/被动传感器,使系统在不牺牲跟踪精度的同时,降低辐射代价。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.
