相控阵雷达事件调度中的时间窗研究

Study on Time Window in Multifunction Phased Array Radar Task Scheduling

时间窗在相控阵雷达事件调度算法研究和调度程序设计中得到了广泛的应用,但对时间窗自身特点的研究往往被忽视。从相控阵雷达数据处理出发,分析了跟踪事件时间窗存在的合理性,建立了α-β滤波和α-β-γ滤波下的时间窗计算模型;分析了搜索事件时间窗存在的合理性,并建立了计算模型;最后将两类事件时间窗计算模型加入到仿真平台中进行仿真,仿真结果证明了模型建立的合理性和有效性。

The application of time window is very extensive in the study on task scheduling algorithm and the design of task scheduling program of phased array radar, but the research on the peculiarity of time window has been neglected. From the data processing of phased array radar, the presence rationality of time window of track task is analyzed. The caleulative model of time window in α-β filtering and α-β-γ filtering is established. The presence rationality of time window of search task is analyzed. The calculative model is established. Finally, the two models are put into the simulation platform to make simulation. The rationality and validity are proved by simulation results.
