Scattering of radio waves by a moving atmospheric rippled layer: A simple model-experiment

Abstract

The results from a simple, light analog modelexperiment are presented. Employing sinusoidal layers made from tinfoil it is found that the experimental results compare favourably with those obtained theoretically [l]. Experiments are then performed using layers of irregular shape. These experiments show that one would expect an atmospheric layer with irregular boundary to give rise to the same general type of permittivity field, from the point of view of degree of isotropy, as that observed in practical transhorizon experiments 131.

Backscatter of electromagnetic waves from a rough layer

“…(23) T = Correlation distance of rough surface (24) (lower boundary of layer) (58), (52a), (36), (64), chapter 2. Since the backscattered power is being calculated in the plane of incidence, the values of v xv , F 3 , g, p Q and R 2 are given by (18), (19), (20), (21) and (22), respectively. L and T are defined by (23) and (24) , respectively.…”

“…so that a and b in (19) and (20) are independent of x. Integrating by parts, (23) Formula (24) is the general solution for a perfectly conducting, one dimensionally , rough surface.…”
