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,文中提出了一种基于空域宽开雷达信号侦察系统的搜索调度方法来优化设计驻留时间。根据驻留时间的长短,将驻留时间分为仅能截获单个雷达脉冲的中等驻留时间和可截获多个雷达脉冲的长驻留时间。搜索开始阶段使用较短的中等驻留时间用于频域的快速扫描,在截获信号后将驻留时间调整为长驻留时间,以便采集雷达信号用于频率及周期结构分析。仿真结果表明,提出的算法可合理利用系统资源,提高系统的截获性能,为现有雷达对抗侦察系统设计提供了有益参考。

Abstract:

Aiming at the problem of long search time and low intercept probability of the radar signal reconnaissance system, a search and scheduling method based on airspace wide open radar signal reconnaissance system was proposed, which was able to optimize the dwell time. According to the length, dwell time was divided into medium dwell time which was only able to intercept a single radar pulse and long dwell time which could intercept multiple radar pulses. Search started with a shorter medium dwell time for fast scanning in the frequency domain. The dwell time was adjusted to a long dwell time after the signal was intercepted to acquire radar signals for frequency and periodic structure analysis. The simulation result showed that the proposed algorithm was able to make rational use of system resources and improve the interception performance of the system, which provided a useful reference for the design of existing radar reconnaissance.

Key words: reconnaissance system, airspace widening, intercept probability, window function, dwell time, resource scheduling
