In the present paper, the potential use of P-band radar signals for the estimation of soil roughness parameters is analyzed. The (IEM) Integral Equation Model is applied to investigate the sensitivity to soil surface parameters of backscattered P-band signals. A new parameter for roughness referred to as Zp, combining the root mean square surface height and the correlation length, is proposed to describe...
In this paper, we propose an analysis of P band radar signal potential to retrieve soil moisture root profile. Our analysis is based on two electromagnetic models, the small perturbation method and the small slope approximation. There models consider electromagnetic scattering from three-dimensional layered structures with an arbitrary number of rough surfaces. Simulations are proposed for different...
