摘　　要：信号的搜索截获是雷达对抗侦察过程中的重要环节。结合雷达对抗侦察的特点,构建了DBF(digital beam forming)体制侦察系统的波位编排模型,分析了已有情报信息对侦察活动的应用价值,给出了时空调度的排序依据,形成了基于信息增益函数的数字波束体制侦察系统的时空调度方法。仿真分析表明,提出的时空调度方法的针对性和效率更高,为现有雷达对抗侦察系统的工作方式提供了有益参考。Radar signal interception is an important link in the process of radar reconnaissance. According to the characteristics of radar reconnaissance,the model of beam position arrangement model of reconnaissance system is built based on digital beam forming technology,and then the application value of existent intelligence information is analyzed. A spatio temporal resource scheduling in the mode of information function is proposed depending on the former work. The simulation analysis shows that the spatio temporal resource scheduling method has more obvious pertinence and efficiency,which provides a beneficial supplement for search strategy of radar reconnaissance.
