摘　　要：以装备电磁兼容性量化需求出发,根据电磁兼容试验数据的特点,将试验结果分为EMI类和EMS两种类型进行分析,提出了EMI和EMS两类试验结果量化表征方法并构建了数学模型。针对EMI类试验数据特点,通过超标数据占比和超标特征两个维度完成了EMI数据的量化表征模型构建;针对EMS类试验结果仅为定性描述这一特点,结合试验过程中的敏感现象,从干扰源及敏感频段两个维度进行量化表征模型构建,通过软件实现了相关量化模型,并通过试验结果量化算例予以验证。以试验结果开展的量化表征研究工作,获得了试验项目的数学量化模型,实现了基于国军标试验标准的电磁兼容试验结果量化表征。Based on the quantitative requirements of equipment electromagnetic compatibility(EMC),the test results can be divided into EMI type and EMS type according to the characteristics of EMC test data.Thus the quantitative representation methods of EMI and EMS test results are put forward and the mathematical model is established in this paper.By analyzing the characteristics of EMI test data,the corresponding quantization representation model is constructed through the two dimensions of standard data share and excessive features.According to the characteristics that EMS test results are only qualitative description and combined with the sensitive phenomena in the measurement process,a quantitative characterization model is constructed from two dimensions of interference source and sensitive frequency band.Besides,the relevant quantitative model is realized by software and verified by experimental measurement.In this paper,the quantitative research of the test results is carried out and the mathematical quantification model of the corresponding test items is obtained,and the quantitative characterization of the EMC qualitative test results based on the national military standard is achieved.The relevant research results of this paper have certain reference significance in system-level EMC performance quantitative evaluation,big data analysis of test results and optimization design of equipment EMC.
