Abstract : In a computer experiment, a corrugated mirrolike reflection surface was made to move horizontally above a plane containing a pair of points representing a bistatic ionospheric radar. The reflection surface was synthesized by the superposition of sinusoidal cylindrical waves that were allowed to move in different directions. A search routine was developed to find the rays that pass through the pair of points and satisfy specular reflection conditions at the surface. Path lengths and their derivatives were computed. The resulting patterns are descriptive and predictive of the effects of wavelike ionospheric perturbations on radio signal characteristics. (Author)
