Abstract
Coherent scattering of laser radiation by a moving random surface was investigated. Fluctuations of the scattered-radiation power were recor ded in field experiments and were used to calculate the velocity of ex tremal points on the random surface. It was found that the distributio n of velocities of these extremal points was close to a direction isot ropic relative to the average velocity vector. The results obtained we re compared with theoretical estimates for a Gaussian model of the sur face.
