Study on Task Interleaving Scheduling of Phased Array Radar Based on Period Division

The waiting time between transmitting and receiving time is not used in conventional task scheduling methods for phased array radar in which dell is impartible, thus system scheduling capacity is restrained. Based on analysis of dell interleaving rules and rule selection guidelines, a dell interleaving scheduling algorithm is proposed based on sampling period division, which can solve the task confliction issue caused by different sampling periods. The scheduling flow, interleaving flow and tactic for overload are also analyzed. The simulation results show that the proposed algorithm improves scheduling capability greatly and achieves better performance compared with conventional task scheduling algorithm.
