摘要

Research passive phased array radar resource scheduling.This paper proposed a passive phased array radar adaptive scheduling algorithm.Based on the passive intercepting and tracking features,the algorithm designed the passive adaptive scheduling algorithm framework,focused on the adaptive generation of the passive task parameters,task priority assessment and scheduling algorithms adaptive implementation,and gave the algorithm performance assessment indicators.Simulation results show that the algorithm can optimize the arrangment of the resources of time,space and frequency resource of the passive array radar,shorten thetarget discovery time,and ensure the tracking stability.%研究被动相控阵资源优化调度.相控阵雷达实现目标跟踪,精度和实时性是主要的指标.针对现有的主动相控阵资源调度不能很好地解决被动环境下搜索截获概率低,跟踪精度差的问题,提出一种被动相控阵雷达自适应调度算法(以下简称为被动自适应调度算法).算法根据被动截获、跟踪的特点,设计被动自适应调度算法的实现框架,重点研究了被动自适应调度的任务参数自适应生成、任务优先级评估及调度自适应执行等算法过程,并给出了被动自适应调度算法性能评估指标.仿真结果表明,该算法能优化安排被动相控阵雷达时、空、频等资源,缩短目标发现时间,保证跟踪稳定性.
