摘　　要：为解决虚拟试验中合成环境数据的统一描述和可交互问题,在分析了合成环境数据表示与转换标准SEDRIS的基础上,对大气、红外、电磁环境建模,并对得到的环境数据进行统一格式的转换,提出了一种基于SEDRIS标准的虚拟试验合成环境建模技术,开发了虚拟试验合成环境原型系统和大气环境可视化,实现了大气、红外、电磁及混合模式等4种试验环境条件下对产品性能的验证与评估;试验结果表明,建立的环境模型具有良好的交互性,建模方法可应用于多种试验环境的描述,为虚拟试验合成环境模型体系、标准规范和辅助工具的形成打下了基础。After analyzing the SEDRIS standard, setting up models of atmosphere, infrared and electromagnetism environment, a meth- od of virtual test synthetic environment modeling based on SEDRIS was proposed to describe the virtual test environment date uniformly, accurately, overall and authority. A virtual test synthetic environment prototype system was developed with atmosphere environment visualization, by which we verify and evaluate the product function under four kinds of experiment environment. The environment models can hand o- ver goodly with each other. Experimental results shows that, the method of set up molds can be applied to describe various experiment envi- ronment, which set foundation for the formation of virtual test synthetic environment modeling system and standard norm.
