国外光学遥感成像系统仿真软件发展综述与思考

Summarization and Consideration of Oversea's Simulation Software Development for Optical Remote Sensing System

光学遥感系统仿真是一个复杂的系统工程,涉及多个交叉学科领域。遥感成像仿真需要严格按照成像的物理过程进行模拟,对各关键环节建立精确的模型,设计标准化的技术流程,最终完成基于地学、光学、大气科学、电子学、传感器设计等多学科和多技术领域交叉融合的系统集成。文章通过广泛调研国外光学遥感仿真软件的应用和发展现状,比较3种典型仿真软件的设计框架和技术路线,分析其发展趋势,为自主研发的光学遥感仿真模拟软件提供借鉴。

Optical remote sensing system simulation is a complicated system engineering which refers to many crossover subjects.Simulation approach should be established according to physical image process and accurate models of key parts.Standard technical program should be designed.The whole system integration should be complished based on several subjects such as earth,optics,atmosphere,electronics and sensor design.Application and development of oversea＇s simulation software for optical remote sensing system was researched.The design framework and technical route of three optical simulation sofeware were compared and the trend was analyzed,which was as a reference for the remote sensing system simulation software of China.
