文章通过对无线电接收机脆弱性机理分析,归纳出不同类别的影响因子。在此基础上提出了基于受体脆弱性影响因子的复杂电磁环境构建方法,解决了宽频段作战单元需要大量电磁环境模拟装备难题。建立了基于电子信息系统信道占有度、频谱重合度、背景信号强度等要素的多激励多响应电磁环境效应“套桶”评估模型,解决了被试对象的客观性与形象性评估问题,为电子信息系统类复杂电磁环境适应性鉴定提供有益借鉴。
By analyzing the mechanism of vulnerability of radio receivers, this paper summarizes the different types of influence factors. Based on this, a method of building a complex electromagnetic environment based on the influence factors of receptor vulnerability is proposed, which solves the problem of a large number of electromagnetic environment simulation equipment required for a wide band combat unit. A multi-excitation and multi-response electromagnetic environment effect “Bucket” evaluation model based on factors such as channel occupancy, spectrum coincidence and background signal strength of the electronic information system is established to solve the objectivity and image evaluation of the subjects, It provides a useful reference for the adaptability identification of complex electromagnetic environment in electronic information system.
