摘　　要：面向通信雷达一体化系统,针对通信和雷达波束调度需求冲突,利用通信业务分集特性,在雷达探测时段内优化雷达探测波位选择,以携带更多通信数据,从而降低引入雷达功能后通信吞吐量的性能损失。通过将该问题建模为二分图最优匹配问题,能够获得低复杂度雷达波束调度算法,实现雷达波束扫描和通信数据传输匹配。仿真结果表明,所提算法能够在保障雷达波位扫描需求的同时,减少引入雷达功能后的通信吞吐量损失。For the joint communication and radar system,in order to resolve the beam scheduling conflict between communication and radar,this paper utilizes the traffic diversity to optimizes the beam scheduling to carry more communication data,thereby reducing the throughput loss due to introducing the radar functionality.By modeling the beam scheduling problem as a bi-partite graph optimal matching problem,a low complexity algorithm can be obtained,so as to realize the matching between radar beam converage and communication data transmission.Simulation results indicate that the proposed algorithm can reduce the communication throughput loss after the introduction of radar functionality while ensuring the requirement of radar beam converage.
