Evaluation of soil surface moisture in Dak Nong province, Vietnam by Sentinel-1 radar image

This study focuses on monitoring the variation of surface soil moisture (0- 1 cm) and ground soil moisture (0÷1 m) in the soil in Dak Nong province using Sentinel-1 radar images received in December 2017. Active radar signals utilized in this method were sent and received using short wave pulses. The intensity of the received signal is compared to determine the scattering coefficient of the surface.
