摘　　要：首先分析电子系统在全寿命过程中面临的电磁环境,通过对干扰模型的时域和频域的分析,形成干扰源的参数化模型,并建立起了复杂电磁环境的干扰源数据库;利用商业电磁场软件和数据库软件作为支撑软件,构建了复杂电磁环境下电子系统抗干扰性能仿真平台,利用商业电磁场软件计算复杂电磁环境对电缆、接收机等设备产生的干扰,将空间的干扰场转换成电缆、设备上的干扰电压,利用数据库技术将计算结果进行存储和管理,并留出数据接口供行为级分析软件调用;对仿真平台的信息处理流程、系统组成和各部分具体实现展开了深入研究,构建了电子系统抗干扰性能仿真平台,用于对电子设备在复杂电磁环境下的抗干扰性能仿真。The electromagnetic environment of electronic system＇s whole life-span was considered. By the analysis of time and frequency domain of the acoustic jamming model, the parameterized model of interference source can be constructed, and the database of interference source under complex electromagnetic environment also can be built. Based on commercial electromagnetic field software and database soft-ware, the electronic system anti-interference performance simulation platform under complex electromagnetic environment was built. With the electromagnetic field simulation calculation of the cables and receivers＇ interference produced by complex electromagnetic environment, the spatial interference field is transformed to the interference voltage of cables and facilities. Then the computed data were stored and man-aged by database software, and the interface data were set aside for the behavioral scale analysis software. The information processing proce-dure, system composition and partial specific implementation of simulation platform were studied intensively, and the electronic system anti-interference performance simulation platform under complex electromagnetic environment was constructed.
