Abstract:

The influence of foam on the sea surface, wind-driven sea waves, lidar parameters, and deviation of the lidar optical axis from the vertical direction on the lidar contrast in the system "oil film–clear sea surface" for pulse remote laser sounding is considered. Analytical expressions have been obtained for the lidar contrast in the system "oil film–clear sea surface" for nadir and slant sounding paths. It is shown that the lidar contrast in the system may substantially degrade for the foam-covered sea surface and deviation of the lidar optical axis from the nadir direction, but still remains fairly sharp at small sounding angles for wide ranges of variations of the driving wind velocity and laser pulse duration.
