Theory for the sounding of multiply scattering media with a bi-static arbitrary polarized lidar systems

摘要

A semi-analytical approach to compute the power and polarization of pulsed return signal in the bi-static sounding of a multiply scattering medium with forward elongated phase function, such as the sea water, tissue or a cloud, which is based on the signal consideration as resulting from the single scattering into backward directions and small-angle multiple scattering into near-forward directions, is briefly described. Possibility of radical simplification of the approach for small angles between the receiver and source axes is shown with using examples of light scattering in the sea water and tissue. Evaluated values of the return polarization as a function of the angle between source and receiver axes in the case of sea water sounding are presented.
