A scheduling algorithm for space target detection of phased array radar based on cost function

This paper focuses on the tracking task scheduling problem of phased array radar for space target. A task model is established and an adaptive scheduling algorithm based on cost function of tasks is proposed, which takes into account the tasks' priority and deadline, and the targets' tracking error and effective observation time. Cost factors are defined, cost function of the task is designed, and implementation steps of the algorithm are given. The algorithm is applicable when observing small and far targets, in this condition, the algorithm schedules pulses by string. The simulation results show that the scheduling algorithm proposed in this paper can effectively improve the scheduling success rate, the time use rate and the task completion ratio. The algorithm proposed can get good performance.
