Abstract

The possibility of reconstructing the cloudiness parameters from measurements with a lidar immersed at depths of 10– 25 m is analyzed. Theoretical analysis is performed by the Monte Carlo method for lidars with realistic technical parameters, two optical types of ocean waters, different optical cloud models, and marine atmosphere in the presence of a fog. It is demonstrated that under typical conditions, cloudiness can reliably be detected up to altitudes of several hundred meters above the sea level. A change of the laser divergence angle and receiver field-of-view angle has a stronger effect on the character of lidar signal reflected from sea water than from cloudiness. A large contribution of multiply scattered radiation to lidar return signals calls for the development of mathematical methods that take it into account to increase the measurement accuracy.
