Experimental studies of dense media scattering

Although volume scattering is an element in perhaps the majority of remote sensing problems, little or no experimental record exists of its scattering behavior. Given the fact that heterogeneous volumes which exist in nature are often very dense in character-a scenario for which confidence diminishes greatly for all theoretical models-it is especially imperative that scattering behavior for such materials be examined carefully in an experimental sense. Furthermore, it is noted that what experimental data does exist is made ambiguous by the presence of contributing scattering mechanisms such as rough interfaces above and below.
