综合自然环境建模与仿真是当前建模与仿真技术研究与应用中关注的焦点之一。本文针对环境特征集关联提取、动态多分辨率建模、综合环境统一重构、面向任务的决策支持等关键技术进行系统阐述。在此基础上研制了复杂低空飞行环境重构与任务决策系统,系统采用一体化分布交互式的联邦架构,具备多分辨率环境仿真、环境对飞行器影响定量评估等功能,为面向工程应用的复杂大气环境重构技术和环境影响仿真评估提供了一种可行的解决方案。

Synthetic natural environment modeling and simulation is one of the spotlights of attention among current researches and applications of modeling and simulation technologies. We expound systematically in this paper the key technologies including relation extraction of environmental characteristics set,dynamic multi-resolution modeling,integrated reconfiguration of synthetic environment,task-oriented decision support. Based on these techniques,a low altitude complex flight environment reconstruction and task decision system was developed. It is of distributed interactive federation architecture and supports multi-resolution simulation and quantitative assessment of the environmental impact on aircrafts. Overall,a feasible solution for engineering applications of complex atmospheric environment reconstruction and environmental impact assessment simulation was presented in this paper.
