Abstract

The paper deals with multipath effects in ionospheric sounding by radio waves with low-Earth orbiting satellites at frequencies slightly above the critical frequency. The multipath effects in inhomogeneous plasma media are eliminated using an additional spatial field processing. This field processing relies on the Double Weighted Fourier Transform (DWFT). We have carried out numerical calculations for multipath propagation caused by radio wave refraction by plasma defocusing lenses.
