Complexity Evaluation Method with Correlation Analysis of Electromagnetic Environment and Spectrum-dependent Equipment

提出了一种基于电磁环境和用频设备相关性的复杂度评估方法。该方法重建了评估体系,针对性地重定义了能量相关度,提出了调制相关度、极化相关度,通过分析用频设备工作与其所处电磁环境的极化相关度、能量相关度、调制相关度进行用频设备所处电磁环境"主观"复杂度评估。仿真结果显示:相同电磁环境下不同设备可产生不同效应,电磁环境的复杂度具有明显的相对性。研究成果可为电磁环境评估、用频设备电磁环境适应性试验、电磁频谱管理等领域提供技术支撑。

A subjective complexity evaluation method with the correlation analysis of electromagnetic environment and spectrum-dependent equipment is presented. This method is used to analyze the subjectivity of the electromagnetic environment by analyzing the energy correlation, modulation correlation and polarization correlation of the spectrum-dependent equipment with the electromagnetic environment. the evaluation system is reconstructed, and the energy correlation is redefined, and the modulation correlation and polarization correlation are proposed. Simulation results indicate that electromagnetic environment has different effects on the different communication systems just as electromagnetism complexities for different targets are distinct. The research results can provide the technical support for the evaluation of electromagnetic environment, the electromagnetic environment adaptability test of spectrum-dependent equipment and the spectrum management.
