多功能相控阵雷达自适应调度算法研究

Research on Adaptive Scheduling Algorithm for Multifunction Phased Array Radar

由于阵列天线的波束捷变能力 ,多功能相控阵雷达可对多个目标交替进行搜索、验证、跟踪等工作方式的操作。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 ,达到优化雷达整体性能的目的。针对多功能相控阵雷达 ,在分析自适应调度算法的设计原则基础上提出一种自适应调度算法 ,并给出具体的性能评估指标。算法能够根据雷达事件的优先级、驻留长度、期望发射时间及时间窗合理地安排一个调度间隔内的雷达事件序列 ,仿真结果验证了调度算法的有效性。

Multifunction phased array radar (MFPAR) can perform not only search and track functions but also confirmation using the beam agile capability. Therefore an effective scheduling mechanism is requied that allocates the time and energy resources of radar to radar functions in such a way that the overall performance of MFPAR is optimized. In this paper, an adaptive scheduling algorithm is presented by analyzing the design pricinple, realization procedure and criterias of performance evaluation. The algorithm can reasonably schedule the dwell requests of each function on the basis of their priority, dwell length, expected time of transmission and time window. The validity of algorithm is proved by the results of simulation.
