文中提出了一种基于层次分析法的复杂电磁环境相似度评估方法,明确了复杂电磁环境相似度评估的原理和设计实现方式,在具体实现时,将电磁环境与构设要求的一致性评估问题转换为对被试装备感知电磁环境的相似度分析。针对复杂电磁环境,采用层次分析思想构建相似度评估体系,基于电磁环境中的信号特征参数,对电磁环境信号在时域、频域、调制域、功率域和极化域等多维度指标进行分析计算,评估电磁环境构设效果,为电磁环境构设方案的调整提供依据。

A complex electromagnetic environment similarity evaluation method based on Analytic Hierar-chy Process(AHP)was proposed,and the principle and design implementation of complex electromag-netic environment similarity evaluation were clarified.In the specific implementation,the consistency e-valuation problem between electromagnetic environment and construction requirements was transformed in-to similarity analysis of the perceived electromagnetic environment of the test equipment.For complex e-lectromagnetic environments,a similarity evaluation system is constructed using the Analytic Hierarchy Process(AHP)approach.Based on the signal characteristic parameters in the electromagnetic environ-ment,the electromagnetic environment signals are analyzed and calculated in multiple dimensions such as time domain,frequency domain,modulation domain,power domain,and polarization domain to evaluate the effectiveness of electromagnetic environment construction and provide a basis for adjusting the electro-magnetic environment construction scheme.
