摘　　要：根据数字阵列雷达的信号处理特征,提出了一种应用于数字阵雷达的波束驻留调度算法.该调度算法以一种在线脉冲交错技术为基础,它使得不同的驻留任务能在满足系统时间和能量资源约束的条件下交错执行,其中,驻留等待期可用来执行其它驻留的发射或接收子任务且不同驻留任务的等待期可在时间上相互重叠.仿真结果表明,由于驻留任务等待期和接收期的充分利用,与传统波束驻留调度算法相比,此算法能有效地降低各类任务丢失率,从而获得更高的系统实现价值率.A dwell scheduling algorithm for DAR is proposed according to the characteristics of signal processing in DAR.The dwell scheduling algorithm is based on an online pulse interleaving technique,which realizes the interleaving execution of different dwell tasks under the time and energy constraints.The waiting durations can be used to transmit beams or receive returning data of other dwells.Furthermore,the waiting durations of different dwells can be overlapped.Simulation results demonstrate that compared with conventional dwell scheduling algorithm, the proposed one can achieve smaller task drop ratio and thus higher hit value ratio for the effective utilization of the waiting and receiving durations.
