Abstract

X-band microwave data from a Synthetic Aperture Radar (SAR) satellite, KOMPSAT-5, was used to produce high-resolution (3 m) surface soil moisture maps over agricultural fields in Victoria, Australia during the winter cropping season of 2019. Primary aim of the experiment was to evaluate the X-band SAR soil moisture for agricultural fields at different crop growth stages. Three paddocks of approximately 100 ha planted with dryland wheat were chosen as experimental fields where ground samples for calibration and validation were collected over five field campaigns scheduled to capture the major growth stages of wheat. The Water-Cloud Model (WCM) was used to delineate the at-surface scattering c..
