摘要

摘要: 提出一种基于简化Volterra级数模型的射频接收机电磁敏感性(EMS,Electromagnetic Susceptibility)行为级仿真方法．利用3阶简化Volterra级数模型对接收机EMS进行分析,根据EMS频响特性,提出一种通用的EMS判据,并给出敏感度阈值仿真求解流程图．弥补了以往在接收机EMS分析时以试验为主,缺乏仿真分析的缺陷．以某双频GPS(Global Positioning System)接收机受连续波干扰为例,对带内和带外(包括镜频和互调)敏感度阈值进行求解．仿真结果表明该方法不仅有效、可行,而且减少了敏感度阈值求解所需的内存空间和仿真运行时间,适应于一般射频接收机的EMS分析,在工程技术领域切合实际．

Abstract: Based on simplified Volterra model, an approach to the simulation analysis of electromagnetic susceptibility (EMS) for radio frequency (RF) receiver at behavior level was presented. Third order simplified Volterra model was adopted to analyze receiver EMS. A general criterion for EMS was proposed according to EMS response characteristics in frequency domain and then flow charts for calculating susceptibility thresholds by simulation were given. This approach is superior to the previous receiver EMS analysis which mainly relies on experiments but lack of simulation analysis. Take dual frequency GPS receiver interfered by continue wave as an example for in-band and out-of-band (including image frequency and intermodulation) susceptibility thresholds calculation. Simulation results show that the proposed method is not only valid and effective, but also reduces internal storage and simulation time which is suitable to RF receiver EMS analysis and practical in engineering and technology field.
