Calculation of signals for oceanographic lidar

摘要

This paper calculates signal levels that would be obtained from oceanographic lidar by solving the one-dimensional transient radiative transfer equation for remote sensing. As an example, detection of fish schools is considered. In this technique a pulsed laser is directed into the ocean, and the time-dependent back-scattered flux is measured at different locations. A large number of parameters such as the spatial and temporal variability of optical properties within the ocean, ocean depth, type of ocean water, and presence of biological matters can significantly affect the radiative transport through oceans. But since the emphasis of the work is on the scattering phenomenon, important parameters associated with it, namely the scattering albedo and scattering phase function distribution, are considered in detail.
