A spectral-polarization method for analyzing the interference pattern of a radio signal

In this paper, we propose a spectral-polarization method for recovering the shape and measuring the displacement velocity of an interference pattern (IP) by analyzing three mutually orthogonal projections of the radio-signal field vector using one receiving antenna. At the first stage of analysis, the complex Doppler spectra of the time variations of these projections are calculated. Then these data are used to determine the spectra of the arrival angles for each component of the spectra. Together with the data on the Doppler shift, this allows us to recover the IP shape and estimate its velocity and displacement direction. Formulas illustrating the proposed method and numerical simulation results demonstrating practical implementation of the idea are given. © 1998 Plenum Publishing Corporation.
