The Soil Reflectance Measurement with Short Wave Infrared Spectrum

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
