Multiple paths on the ocean surface

A realistic model of propagation affected by multiple paths on the sea surface is considered in an effort to develop a computer program for use in studying systems work operating in such an environment. The compatibility of laws of hydrodynamics with those of statistics are examined in order to obtain an appropriate description of the sea surface. A linear model is proposed and its validity is assessed. The statistics of a diffuse signal in the ocean surface environment are obtained for direct signals, coherent signals, and diffuse signals. The choice of an electromagnetic theory to describe the effects of backscattering is explored. The model proposed describes as correctly as possible the spatio-temporal correlation of the signal and introduces oceanographic data from experiments.
