Abstract:

An improved model is reported for the effect of surface roughness on coherent scatter of microwaves from moderately rough terrain and sea surfaces. This model gives agreement with microwave and acoustical experimental data for surface height standard deviations as much as 400 larger than for a widely accepted model discussed by Beckmann and other investigators. The improved agreement with data is achieved by assuming a symmetrical exponential probability density of the surface height random variable. This model lends itself to an interesting physical interpretation of the stochastic process associated with the surface profile.
