Abstract A method of snow covered ground simulation using the first-order radioactive transfer model is described in this paper. In this method, three parts of the echo are taken into account, i.e., top surface scattering, volume scattering and subsurface scattering. A new surface scattering model——AIEM, instead of the IEM model, is used to deal with the surface scattering problem. Finally, the improved method is verified using the measured data of 1995 from the University of Michigan.
