To Study the Volumetric Soil Moisture Through Microwave Remote Sensing
Soil moisture is an importance parameter that is essential for decision-making process to improve soil resource and crop production. However, determining and monitoring of spatial variations of soil moisture by field research is too complicated and difficult in limited time. L-band of Microwave is known as penetrated satellite data as it can detect character of subsurface features in agriculture. This study aimed at initiating a relationship between soil moisture from field and L-band polarization from space. Both sources of statistical data were subjected to correlation analysis. To examine scattering properties of varied soil moisture. Furthermore, a series of tests were accomplished to derive the correlation of different polarizations of L-band. The methodology comprises three main steps; ground measurement data, analysis of the polarization of microwave data and, evaluation of the potential of L-band polarization relate with soil moisture. Soil moisture were analysis at two depths as 5 and 30 centimetre. The results illustrated that the correlations between L-bans and soil moisture depths predicted by each method were highly correlation. Furthermore, L-band polarizations were used able to predict the soil moisture for agricultural management. In particular, L-band polarization model developed for investigate of soil moisture have the potential to detect rapidly and inexpensively.
