摘　　要：针对单波束多功能机载相控阵雷达的资源分配问题,提出一种自适应搜索加跟踪(track and search,TAS)调度算法。该算法以调度间隔为周期,基于先前调度任务的处理结果实时生成当前的任务请求集合,以跟踪类型任务竞争时间资源,搜索任务一直等待空闲时间片为准则,实现搜索和跟踪的协同调度。此外利用波束位置、任务类型和预测速度信息,实时分配各执行任务的工作波形。仿真结果表明,该算法能够合理调度各类跟踪请求事件和搜索事件,同时具有自适应调整执行事件的跟踪时间间隔和探测波形的能力。The problem of resource allocation is central to the multifunction airborne phased array radar with a single beam. To solve it, an adaptive scheduling algorithm of track and search （TAS） mode is proposed. Taking the schedule interval as a cycle, the proposed algorithm generates the current task request set based on the processing results of the previous scheduled tasks. Then using the principle that tracking requests compete for the time resources while search tasks wait for idle time slices all the time, a coordination scheduling for search and tracking is implemented. Furthermore, the information of beam positions, task types and predicted velocities are used to allocate the waveforms of executed tasks in real time. Simulation results show that the proposed algorithm can reasonably schedule all kinds of tracking requests and search events, and also has the -ability-to adaptively adjust the tracking time interval and the detection waveform.
