基于SEDRIS的虚拟试验合成环境建模技术研究

为解决合成环境的统一描述和可交互问题,在分析合成环境数据表示与转换标准SEDRIS基础上,提出了基于SEDRIS的虚拟试验合成环境建模方法,针对大气、红外、电磁等3类自然环境,给出了实现环境数据表示和转换的技术途径。通过系统开发,实现了4种试验环境条件下对产品性能的验证与评估,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。

Research on Virtual Test Synthetic Environment Modeling Based on SEDRIS

After analyzing the SEDRIS standard, setting up models of atmosphere, infrared and electromagnetism environment, a method of virtual test synthetic environment modeling based on SEDRIS was proposed to describe the virtual test environment date uniformly, accurately, overall and authority. By development virtual test synthetic environment prototype systems, we verify and evaluate the product function under four kinds of experiment environment. The environment models can hand over goodly with each other. The method of set up molds can be applied to describe various experiment environment, such as road spectrum and wind fields, which set foundation for the formation of virtual test synthetic environment modeling system and standard norm.
