Abstract
We assess the potential for measuring spatial patterns of soil moisture using SAR at spatial resolutions down to 15m. Highly detailed ground data on soil moisture and dielectric constant were collected in the 10.5 ha Tarrawarra experimental catchment in south-eastern Australia. C-band SAR measurements by ERS-1, ERS-2 and AirSAR provided no useful information on the spatial moisture pattern. Empirical comparisons suggest that L and P-band AirSAR data contain useful information on the soil moisture pattern, but this could not be extracted using a semi-empirical inversion algorithm. The spatial average moisture was successfully obtained from the L-band AirSAR data.
