摘　　要：针对雷达信号侦察系统搜索时间长、截获概率低的问题,提出一种基于空域宽开雷达信号侦察系统的时频联合搜索调度方法。采用频域分区的策略,根据子频域的权重调整搜索帧周期;根据驻留时间的长短,采用中等驻留时间快速搜索引导长驻留时间采集的分步搜索方法,优化设计驻留时间。仿真结果表明该算法可合理利用系统资源,提高系统的截获性能。Aiming at the problem that the radar signal reconnaissance system has long search time and low intercept probability,a time-frequency joint search scheduling method based on airspace wide open radar signal reconnaissance system is proposed.The frequency domain partitioning strategy is adopted to adjust the search frame period according to the weight of the sub-frequency domain.According to the length of the dwell time,a step-by-step search method for quickly searching for long well time acquisition is adopted to optimize the design dwell time.The simulation results show that the algorithm can make rational use of system resources and improve the interception performance of the system.
