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 Kirchhoffs 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.
