【摘要】：随着遥感技术的发展,红外谱段遥感器性能不断提高,红外遥感在防灾减灾、军事目标识别与探测、资源普查等领域都得到了更广泛的应用。与此同时,先进的红外遥感器也对遥感卫星总体优化设计提出了更高的要求。与可见光不同,红外谱段目标特性反映了地物的发射辐射特性,不仅与地物的表面热力学特性相关,还与其周围地理环境、大气环境有着密切的联系,因此对红外谱段目标特性的分析也更为复杂。本文研究目标是在地物辐射特性研究、大气传输模型研究以及遥感器模型研究等关键技术攻关的基础上,初步建立一个专业化的热红外遥感数据仿真模拟系统集成架构。在技术上实现基于遥感器设计参数、地球环境背景和大气状况,模拟出一幅真实的图像和任意波段组合的多波段图像,以检验遥感器设计的合理性。本文的主要贡献包括以下几点:(1)面向陆地表面遥感场景仿真分析工作需要,设计并实现包含地表反射率、地表发射率、地表净辐射、表观热惯量、感热通量、潜热通量、地表粗糙度等参数在内的综合、统一、标准的红外地物波谱数据库。(2)设计红外遥感图像仿真系统算法集成软件的体系结构和功能结构,软件实现地表辐射场模拟、大气传输模拟及光学传感器模拟等模型和算法,无缝集成上述模型和算法,实现了一个界面统一、操作简便及运行高效的红外遥感图像仿真系统算法集成软件实物。热红外遥感成像系统的设计和性能评价离不开计算机仿真技术的支撑,本文研制的红外遥感图像仿真系统算法集成软件,有助于卫星总体在设计阶段进行需求分析、任务分析工作;结合全链路成像仿真系统,为深入进行红外遥感图像质量评价提供有力工具。
[Abstract]:With the development of remote sensing technology, infrared spectrum sensing performance improving, infrared remote sensing in disaster prevention and mitigation, military target recognition and detection, resource survey and other fields have been widely used. At the same time, the advanced infrared remote sensor but also on the overall optimization of remote sensing satellite has put forward higher requirements and visible different design. The infrared spectrum, the target radiation characteristics reflect the features of objects, not only related with the surface thermodynamic properties of objects, but also with the surrounding environment, is closely related to the atmospheric environment, so the analysis of infrared spectral characteristics of the target is also more complex. The goal of this research is to study the radiation properties in the object, basic research research on key technology of atmospheric transmission model and remote sensing model research on preliminary thermal infrared remote sensing data simulation of a professional simulation system integrated framework established in technology. Design and implementation of remote sensor parameters based on the earth environmental background and atmospheric conditions, to simulate the multi band image of a real image and multi band combination, in order to prove the rationality of remote sensor design. The main contributions of this thesis include the following: (1) for land surface remote sensing scene simulation analysis work requirements, design and implementation include the surface reflectance, surface emissivity, surface net radiation, apparent thermal inertia, sensible heat flux, latent heat flux, comprehensive, uniform surface roughness parameters, infrared spectral database standard.

Real design and performance evaluation of thermal infrared remote sensing imaging system cannot do without the support of computer simulation technology, the algorithm of infrared remote sensing image simulation system integrated software developed in this paper, contribute to the satellite system in the stage of design requirement analysis, task analysis; combined link imaging simulation system. To provide a powerful tool for further infrared remote sensing image quality evaluation.
