Abstract

By using spatial processing of field based on the double weighted Fourier transform (DWFT) method, we suggest eliminating effects of multipath propagation on results of field measurements during signal propagation in a smoothly inhomogeneous medium. We explore the possibility of eliminating effects of multipath propagation from results of scattered-field measurements during signal focusing by a local plasma irregularity and refraction by several local irregularities. We present results of the numerical simulation of phase after the DWFT spatial processing and without it for multipath propagation of radio signal.
