Electromagnetic Wave Reflection From Irregular Plasma Layers
Abstract
The general theory describing reflection of electromagnetic waves from irregular reflectors was formulated by using path integral techniques (Dashen, 1979; Flatte, 1979). The general formulae reproduce the well known reflection coefficients for wave scattering from random rough surfaces derived by using Kirchhoff's theory or perturbation theory (Ogilvie, 1991). The theory was used to determine the degradation of an OTH radar signal scattered from irregular Artificial Ionospheric Mirrors (AIM). The cases of density irregularities induced by fluctuations in the ambient neutral density and by fluctuations in the heater power were separately examined. Scaling laws and bounds for minimal signal loss were derived.
