【摘要】：高光谱成像技术将遥感成像和光谱测量技术有机结合起来，可以同时获得目标的空间和光谱辐射信息，极大地提高了目标探测的能力，在军事和民用方面都获得了广泛应用。然而随着高光谱技术的发展，现有的高光谱实物实验平台越来越不能满足高光谱成像的要求，为此，，构建高光谱场景仿真系统对于高光谱成像系统的设计具有重要意义。本文对高光谱三维红外场景仿真系统进行了研究。文中首先分析了高光谱遥感成像的机理，对典型地物目标（草地、岩石和水体）光谱反射特性建模。其次研究太阳辐射、天空背景辐射以及大气效应对地物目标反射的影响，并对环境辐射特性进行建模。然后研究了高光谱遥感成像中的成像系统效应，并对光学系统、探测器系统、信号处理电路系统和噪声特性进行建模。最后基于OGRE渲染引擎构建高光谱场景仿真系统软件，并对近红外波段地物场景进行仿真分析。
[Abstract]:Hyperspectral imaging technology combines remote sensing imaging with spectral measurement technology, which can obtain the spatial and spectral radiation information of the target at the same time, which greatly improves the ability of target detection. It has been widely used in both military and civil fields. However, with the development of hyperspectral technology, the existing hyperspectral physical experimental platform can not meet the requirements of hyperspectral imaging. It is very important to construct a hyperspectral scene simulation system for the design of hyperspectral imaging system. In this paper, the hyperspectral 3D infrared scene simulation system is studied. Firstly, the mechanism of hyperspectral remote sensing imaging is analyzed, and the spectral reflection characteristics of typical ground objects (grassland, rock and water) are modeled. Secondly, solar radiation is studied. The effects of sky background radiation and atmospheric effect on the reflection of ground objects are modeled. Then, the imaging system effects in hyperspectral remote sensing imaging are studied, and the optical system and detector system are studied. Finally, the hyperspectral scene simulation system software based on OGRE rendering engine is constructed, and the near infrared terrain scene is simulated and analyzed.
