Abstract:

An RF scattering model which is consistent with existing IVORY CORAL and PRAIRIE SMOKE experimental measurements has been developed for the on frequency signal component scattered from the heater induced ionospheric irregularities. The model is intended primarily for scatter communications systems application and further to aid in the theoretical and experimental efforts to understand the heater-ionosphere interaction phenomenon. The model presented here is based on the theory of weak scattering Born approximation developed by Booker for the case of anisotropic field aligned Gaussian irregularities. The characteristics of the irregularities in the heated volume are specified generally by a two dimensional Gaussian autocorrelation function having a scale size T transverse to the magnetic field and a scale size L along the field. The model predictions were found to match well with the observed radar cross-sections.
