| 摘 要： | 利用DG-2短波红外光谱辐射计，得到了短波红外波段不同含水量下的土壤反射率。分析了土壤短波红外区的光谱特性，表明1.6μm附近有较好的光谱响应，以及该波段反射率与含水量有较好的负相关性的特点。所得结论为气象卫星短波红外区域的通道选择提供了可行性的依据。该实验为卫星遥感数据的处理、分析和判读积累了部分实测资料。

| Abstract: | Using DG-2 short infrared spectroscopic radiometer the soil reflectances for the short wave infrared window area with various soil moistures are measured. The spectroscopic characteristics are investigated. The results show that the spectroscopic response in about 1.6μm is obvious, and the anticorrelation between the reflectance of soil and the moisture content with that wavelength is clean. The measuring results provide feasibility basis for the choice of short wave infrared channels of remote sensing instruments of meteorological satellite, and this experiment is also useful for processing, analysis and identification of meteorological satellite remote sensing information |
