基于场景定义的电磁环境模拟系统设计

摘要

The simulation of electromagnetic environment is the basis of the research on electromagnetic environment effect .Aiming at the problem of the realistic construction of electromagnetic environment ,a design method of electromagnetic environment simulation system is brought based on the design idea of the e‐lectromagnetic environment consistent with the receptor real time generation and scene definition . The framework of the system ,the definition of the scene and the design of the electromagnetic signal generation are given ,and the key technologies of system implementation are analyzed . The custom of electromagnetic environment scene is achieved by the edit of entity ,signal environment and behavior using the scene definition unit ,and the signal generating unit is drove ;the idea of software radio is adopted by the signal generating unit ,and the real signal environment is produced based on the signal simulation of predefined scene .%电磁环境的模拟是开展电磁环境效应研究的基础。针对电磁环境逼真构建的问题，基于面向受体实时生成与场景定义相一致的电磁环境的设计思想，提出了一种电磁环境模拟系统设计方法。给出了系统结构框架、场景定义设计和电磁信号生成设计，并对系统实现的关键技术进行了分析。场景定义单元通过对实体、信号环境、行为的编辑实现电磁环境场景自定义，并驱动信号生成单元；信号生成单元采用软件无线电思想，基于预定义场景进行信号模拟，产生真实信号环境。
