红外视景仿真技术及其研究进展

Overview of Infrared Scene Simulation

从红外视景仿真技术意义出发,介绍了其所包含的几个基本部分;从目标辐射建模、背景辐射建模和大气建模三方面,总结了国内外红外视景仿真技术发展历程和状况。其中列举了国外多个典型红外视景仿真软件和几个较完善红外辐射模型,并统计了2000年以来国内高校在红外视景仿真方面的研究情况。统计数据表明,多个发达国家的红外视景仿真技术已逐步趋于成熟和产品化,而国内尚未开发出功能较完善的红外视景仿真系统,只能仿真较简单场景。

Infrared scene simulation is the extension of scene simulation in IR wavebands, which improves the comprehension and interpretation of thermal IR imagery, and leads to more efficient usage of IR sensors. The hasic components are introduced first, which mainly include target modeling, background modeling and atmospheric radiation modeling. Then, the emphasis is put on the research progresses of the technology at home and abroad. Some typical IR simulation software packages and their performances are enumerated in a table. Furthermore, several comprehensive thermal models are briefly introduced. Compared with the external developments, the research statuses of several internal universities arc summed up into another table. It is evident that the external infrared scene simulation has gradually heen sophisticated and productive. Contrarily, comprehensive infrared simulation systems are rarely presented in current internal market.
