dc.description.abstractEnField measurements of dielectric properties of hyper-saline deposits were realized over an arid test site located in Death Valley (CA). The dielectric constant of salt and water mixtures is usually high, but can show large variations depending on the considered salt. We confirmed values observed on the field with laboratory measurements, and we used these results in order to model both the amplitude and phase behaviors of the SAR signal, at C, and L-bands. Our analytical simulations allow to reproduce specific copolar signatures observed in both AIRSAR and SIR-C data, corresponding to the saltpan of Cottonball Basin.
