Abstract : Knowledge and understanding of the propagation of electromagnetic waves through the ionosphere, ionospheric irregularities, and artificial electron clouds provide the Air Force with information and criteria needed for the solution of problems involving discrimination, detection, and communication. Because of the difficulties encountered in obtaining analytic and accurate numerical solutions to problems of practical interest, approximate solutions provide a useful alternative and, in addition, indicate relations among the important parameters which may be obscured in a more complicated solution. The present report is concerned with the application of perturbation techniques to the scattering of electromagnetic waves by an underdense ionospheric layer. (Author)
