Abstract :
The authors study electromagnetic wave scattering from a buried object under a two-dimensional (2D) random rough surface using the sparse-matrix canonical-grid (SMCG) method. Both the scattering coefficient (normalized RCS) and angular correlation function (ACF) are calculated based on azimuthal angular averaging. It is found that the ACF is more effective in suppressing the clutter due to the rough surface scattering, and the cross-polarization components of ACF can be more useful than co-polarization components for the detection of the buried object
