A Stochastic Simulation of Low Grazing Angle, Forward Scatter, Over-Water Multipath Effects

Abstract : This report describes a stochastic model and a simulation of low grazing angle, forward scatter, over-water multipath applicable to microwave frequencies. The model is based primarily on the work of Charles Beard, using a coherent and an incoherent vector summation to describe the reflected signal. A second order stochastic model and an associated stochastic simulation are described. Controlling parameters are sea state, radar frequency, transmitter/receiver geometry, and radar antenna patterns. A model is suggested for the incoherent spectrum when one or both radars are moving.
