地球表面的物体温度一年四季一般在+40℃至-40℃之间,根据维恩位移定律,它们辐射的电磁波峰值波长在9.26至12.43微米红外光谱范围内,因此可用红外遥感(一般波段在8至12.5微米)来探测目标的温度场。定量的温度场数据可用于地热调查、土壤分类、海洋渔群探测、地质找矿、水资源考察等场合。下面就如何运用红外遥感手段汁算目标温度场的若干方法,分别从理论上加以推导论述。
The temperature of the Earth’s surface is generally between + 40 ° C and -40 ° C throughout the year. According to Wien’s law of displacement, the peak wavelengths of electromagnetic radiation radiated by them are in the infrared spectral range of 9.26 to 12.43 microns. Therefore, infrared remote sensing 8 to 12.5 microns) to detect the target’s temperature field. Quantitative temperature field data can be used for geothermal survey, soil classification, marine fisheries exploration, geological prospecting, water resources inspection and other occasions. Below on how to use infrared remote sensing means to calculate the target temperature field of a number of methods, respectively, from the theoretical deduction.
