相控阵雷达自适应资源调度研究

Research into Adaptive Resource Scheduling of Phased Array Radar

相控阵天线在计算机控制下能以微秒量级的时间形成和定位雷达波束,完成目标搜索、目标确认、目标跟踪及识别等。为此,需要一种调度策略以有效地分配雷达时间和能量等资源。在分析自适应资源调度设计原则和性能指标的基础上,提出了一种具有时间窗约束条件的自适应资源调度算法,该算法根据事件的优先级、期望发射时间、驻留时间及约束时间窗,能够实现合理地安排一个调度间隔内的雷达事件序列,并对美国地基雷达(GBR)的资源调度进行分析研究,对某型雷达的作战任务规划具有指导意义。

Under the control of computer,phased array antenna can form and locate the radar beam in microseconds, and finish many functions such as target searching, target determining, target tracking,recognition and so on. To this end, it is necessary to have an adjustment strategy to allocate the resources like radar time and energy effectively. Based on the analysis of design principle and performance indexes of adaptive resource scheduling, the paper proposes a adaptive resource scheduling algorithm which has time window constraint. According to the priority, expected launch time,residence time and constraint time window of radar event,the algorithm can reasonably arrange radar event sequence in a scheduling interval, and make an analysis on the re source scheduling of American ground based radar （GBR）,which has some guidance significance for the combat mission planning of a certain radar.
