Analysis of IR characteristic of the urban street based on the thermal infrared radiance simulation with aggregation model

The reflected radiation and the emitted radiation from buildings have important influence on the characteristics of infrared remote sensing of the urban street in the urban environment. Firstly, an analyzing of the transmission process of the infrared radiation in the urban canyon was done based on the thermal infrared radiance simulation with aggregation modeling (TITAN) model. Secondy, based on the Cook-Torrance model, a theoretical analysis was conducted to calculate and analysis the contribution of the reflected radiation and the emitted radiation from adjacent walls and windows to the infrared remote sensing characteristics of the urban street. The main factors that affected the radiation form the adjacent buildings were discussed. It can provide theoretical basis for the research of the infrared characteristics and the research of the infrared remote sensing characteristics in the urban environment. It can be applied to the fields of infrared dynamic scenes simulation and urban remote sensing efficiently.
