Quantification characterization technology of electromagnetic compatibility based on test results

  • 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。
