| 摘 要： | 针对相控阵雷达波束快速扫描能力,提出了一种基于时间指针的相控阵雷达在线脉冲交错调度算法。首先建立了雷达驻留任务模型并分析了调度约束条件,然后引入时间指针来指向当前调度分析时刻,分别从波束的角度和脉冲的角度分析了驻留任务交错的几种方式,并给出了三种脉冲重叠方式的时间约束条件,最后在满足时间和能量资源约束的条件下,选取综合优先级最高的雷达驻留任务进行调度。仿真结果表明,与基于收益的调度算法相比,此算法能有效地降低任务丢失率,提高时间利用率和能量利用率。

| Abstract: | According to the ability of waveform agility of phased array radar, a time pointer-based on- line interleaving algorithm for phased array radar is proposed. Firstly, a reasonable beam dwell scheduling model is built and the scheduling constraints are analyzed. Secondly, based on the time pointer, several pulse interleaving ways are analyzed from the aspect of beam and pulse, and an expression of time constraint is giv- en for three pulse overlapping ways. Finally, the algorithm selects the highest priority radar dwell task under time and energy constraints. The simulation results demonstrate that the fast pulse algorithm can control the task drop rate in a low zone and obtain high system utility in dense tracking condition. |
