城市环境中建筑物的反射辐射与发射辐射是影响城市街道红外遥感特性的重要因素。基于红外辐射聚合模型(Thermal infrared radiance simulation with aggregation model,TITAN),对红外辐射在城市街道场景中的传输过程与分配过程进行了分析,基于Cook-Torrance模型,理论上计算并重点分析了邻近街道的建筑物窗户与墙壁的反射辐射与发射辐射对街道红外辐射特性的贡献,对影响邻近环境辐射的主要因素进行了讨论,为城市场景中景物的红外辐射特性研究和红外遥感特性分析提供了理论参考。 Reflection radiation and emission radiation of buildings in urban environment are important factors that affect the infrared remote sensing characteristics of urban streets. Based on the Cook-Torrance model, the transmission and distribution of infrared radiation in urban street scenes are analyzed based on Thermal infrared radiance simulation with aggregation model (TITAN). Based on the Cook-Torrance model, the calculation and analysis of the adjacent streets The contribution of reflection radiation and emission radiation to the street infrared radiation characteristics of windows and walls in buildings is discussed. The main factors affecting the radiation of neighboring environment are discussed, which provides a theoretical basis for the research on infrared radiation characteristics and infrared remote sensing properties of urban scenes reference.
