In this paper, we study backscattering from the ocean using 3D numerical simulation of Maxwell's equation (NMM3D). Previously we used NMM3D to compute backscattering and emissivity of rough soil surfaces for active and passive microwave remote sensing of soil moisture [1, 2] at L, C, X and Ku bands. The computed results were in excellent agreement with measurement data for co- and cross-polarizations...
Active and passive microwave remote sensing data holds great potential for soil moisture estimation. Herein, the application of the Least Squares Support Vector Machines (LS-SVM) to soil moisture inversion is explored. Simulation is carried out using different sets of training and test data. The methods have been applied to two sets of data to retrieve bare-surface soil moisture, and the rms error...
The partially coherent approach of dense media radiative transfer (DMRT) has been extensively applied to study the wave propagation and scattering inside dense media such as terrestrial snow [1–5]. In the DMRT partially coherent approach, the coherent part is obtained by solving Maxwell's equations over several cubic wavelengths of statistically homogeneous snow volume to compute the phase matrix,...
