Abstract :
SAR signals over a small catchment are qualitatively evaluated using the data collected in a multi-sensor airborne campaign. Results are used to address the problems in relation to soil moisture estimation. It is found that a short grass canopy does not have a significant effect on the SAR echoes. Polarization ratios may not be adequate for soil moisture retrieval purposes
