In volume scattering, the return signals depend not only on radar system parameters, such as wavelength, polarization, and incident angle, but also on the structure and the heterogeneity of the imaged object. Similar to diffuse surface scattering, volume scattering contributes significant amounts of radar backscatter and is positively related to the degree of discontinuity of ice volume such as cracks, air inclusions (or air bubbles), water pockets, and impurities [8,13].
