The problem of retrieval of depth profiles of scattering coefficient from polarization of pulsed lidar return

摘要

In this paper, the technique to retrieve stratification of scattering properties of multiply scattering media with highly elongated phase functions, such as ocean waters, from the time-dependent polarization degree of lidar waveforms measured by mono static lidars with large field-of-views is analyzed. Retrieval errors connected with use in the technique of the equation defined within the theory with initial infinitely wide beam are estimated. An approach to improve retrieval through introducing the correction function into the equation used to invert measured values of the polarization degree of lidar waveforms is suggested and retrieval by this approach is tested.
