A model for calculation of the depolarization of a laser beam propagating through a water cloud is described, in which multiple scattering up to sixth order is included using a Monte Carlo technique. The influence of beam geometry, drop size distribution, and cloud extinction coefficient on the depolarization is discussed. Good agreement between calculated and measured profiles of the depolarization observed in water clouds has been obtained.
