Online pulse interleaving task scheduling for multifunction radar

摘要

An efficient scheduling algorithm is the key to handling various tasks simultaneously for the multifunction radar. A radar task comprises the transmitting, waiting and receiving durations. The waiting duration can be utilized to transmit or receive signals. This scheduling technique is called pulse interleaving. In this article, a novel online pulse interleaving scheduling algorithm is proposed. The algorithm divides the pulse interleaving analysis into the time resource and the energy resource analyses and adaptively interleaves different types of tasks. Thereby the pulse interleaving can be simplified, the waiting durations can be fully utilized, and different workload situations can be well matched. Simulation results show that the proposed algorithm achieves higher successful scheduling, time utilization and high-value ratios compared with the three existing algorithms while maintaining an efficient runtime.
