基于多频段信号统一建模的电磁空间安全监测

Electromagnetic Space Security Monitoring Based on Unified Modeling of Multi-Band Signals

随着移动通信、宽带雷达等技术的快速发展,电磁空间中使用的辐射源种类、数量迅速增加,频谱范围已经覆盖了从短波到毫米波等多个频段。传统监测系统已无法满足跨频段有效监测且信号样式愈发多样性的电磁环境,针对L、S、C、X、Ku五个波段的雷达信号,设计了一套基于多频段信号统一建模的电磁空间安全监测系统,能够对五个波段内的雷达设备进行高鲁棒性、高准确性的辐射源个体识别,五个频段内的雷达个体平均识别准确率达到86.23%。且该系统能够监测的频率范围从1 GHz至18 GHz,包括频率跳变、抖动、脉冲重复间隔参差等复杂信号样式。

Traditional monitoring systems can no longer meet the requirements of cross-band effective monitoring and increasingly diverse electromagnetic environment with signal styles.Aiming at the radar signals of L,S,C,X and Ku bands,this paper designs a set of electromagnetic space security monitoring system based on unified modeling of multi-band signals,which can identify individual radiation sources with high robustness and accuracy for radar equipment in the five bands.The average individual recognition accuracy in the five frequency bands reached 86.23%.The system can monitor frequencies ranging from 1 GHz to 18 GHz,including complex signal patterns such as frequency jump,jitter,and uneven pulse repetition intervals.
