Soil Permittivity Estimation Over Croplands Using Full and Compact Polarimetric SAR Data

Soil permittivity estimation using Polarimetric Synthetic Aperture Radar (PolSAR) data has been an extensively researched area. Nonetheless, it provides ample scope for further improvements. The vegetation cover over the soil surface leads to a complex interaction of incident polarized wave with canopy and subsequently underlying surface. This paper introduces novel methodology estimate croplands full compact polarimetric modes. proposed method utilizes scattering-type parameters, θ FP xmlns:xlink="http://www.w3.org/1999/xlink">CP , respectively. These scattering type parameters are function Barakat degree polarization. considers X-Bragg model In particular, these explicitly account depolarizing structure scattered while characterizing targets. Thus, depolarization information in terms roughness gets inherent importance unlike existing parameters. Therefore, technique enhances expected value inversion accuracies. study validated major phenology stages four crops UAVSAR full-pol simulated pol SAR ground truth collected during SMAPVEX12 campaign Manitoba, Canada. estimated RMSE 2.2 4.69 FP 3.28 5.45 CP along Pearson coefficient, r ≥ 0.62.
