摘　　要：分析了雷达对抗侦察接收机的截获概率和平均截获时间与波束驻留时间和搜索帧周期之间的关系，针对雷达对抗侦察中的情报收集型侦察任务和目标确认型侦察任务两种任务类型，提出了适用于数字波束形成（DBF）技术的调节驻留时间法（ADT）和调节搜索帧周期法（AFP）两种空域优化搜索方法。最后进行了实例仿真，验证了两种优化方法的有效性。In this paper, the relationship between the interception probability and average interception time of radar reconnaissance receiver, and the relationship between the beam dwell time and search frame period are analyzed. Then, two optimized methods, the Adjust Dwell Time （ADT） and Adjust Frame Period （AFP）, are proposed aimed at the two types of reconnaissance tasks, which are intelligence-gathering task and target-confirming task. Finally, an example simulation is done, and the effectiveness of those two optimized methods is demonstrated.
