| 摘 要： | 相控阵雷达的任务调度是影响相控阵雷达整体效能的关键因素,应根据雷达搜索和跟踪模式的不同需求,需要对计算资源进行有效调度。对于机械旋转相控阵雷达而言,其额外增加的机械约束特征决定了调度过程本身也需要大量计算资源。基于多核DSP并行结构对旋转相控阵雷达任务规划进行了不同资源的优化。模拟运行数据表明,基于多核DSP调度的架构可在有效实现基于预估计的任务调度过程,提高系统层面雷达任务管理的调度效率。

| Abstract: | Task scheduling is one of the key elements to affect entire efficiency of phased array radar(PAR).In order to effectively schedule the radar resources,different requirements of radar searching and tracking should be considered.For mechanical PAR,the procedure of task scheduling,influenced by additional mechanical characteristics,also needs enormous calculating resources.Based on multi-core DSP parallel architecture,task scheduling and corresponding resources for rotate PAR is optimized in the paper.According to the simulation and emulation results,the parallel architecture based on multi-core DSP can effectively realize task scheduling procedure based on pre-estimation,and improve overall efficiency of PAR task scheduling. |
