Numerical analysis of surface clutter in GPR scenarios
The clutter caused by scattering from a rough air-ground interface is analyzed numerically. The simulations have been done using Monte-Carlo approach. An ensemble of surface profiles with the desired probability distribution and autocorrelation spectrum is simulated numerically. For each realization of the interface profile the scattered field has been calculated by a deterministic approach. Averaging of the scattered filed over ensemble of the surface realizations has been done numerically. Statistical properties of the scattered field have been analyzed. It has been found that the magnitude of the surface clutter caused by reasonably smooth surfaces can exceed easily the mean value of the ground reflection. Furthermore it is demonstrated that if the magnitude of the surface clutter is considerably less than the mean value of the ground reflection then the correlation function of the reflected field coincides with the correlation function of the rough surface.
