摘要
The present invention seeks emissivity or reflectivity as the ratio of the brightness temperature and surface temperature from satellite observations , surface using the polarization properties of the microwave according to the properties of the two calculated reflectivity (Reflectivity) and , in view of the fact that the physical properties ( dielectric constant) is different from the water and soil , the method of detecting the moisture of the soil surface . According to the present invention, by direct observation is not possible, or constrained region , or calculating the soil water content to the area of the other countries , and produce a valuable material in the national economy , agriculture , emergency , etc. that have a direct effect can substantially contribute to the industrial sector . ; 展开▼
