A Model for Field Aligned Scattering (FAS) from Heater Modified Ionosphere

Abstract

The paper describes the current status in the development of the on- frequency scattering model. The presentation adopts a format that is intended to orient the model toward eventual application for systems evaluation. The physical description of the scattering medium which constitutes a basic component to the model is derived from the observations currently at hand. The radar scattering properties of the disturbance are described physically by presenting the concepts of aspect sensitivity and surface of specularity for scattering by way of an optical analogy. The mathematical part contains two levels of sophistication in the model treatment. The simpler approach offers an approximate analytic solution and thereby a first-order systems evaluation capability without resorting to a complex computer code. Finally, a flow chart is given for computer adaptation of the scattering model in its general form.
