Electromagnetic scattering from arbitrary random rough surfaces using stabilized extended boundary condition method (SEBCM) for remote sensing of soil moisture

In this paper, the stabilized extended boundary condition method (SEBCM) is developed based on the classical EBCM to solve both 2D and 3D electromagnetic scattering from arbitrary random rough surfaces. The SEBCM gives accurate full wave solutions over large range of surface roughnesses and medium losses, which are far beyond the validity range of analytical methods, and perform with much higher efficiency than numerical methods. These properties make SEBCM a competitive forward model in the inverse problem for soil moisture retrieval from radar measurements.
