Abstract

This article describes the correlation function and the angular energy spectrum of scattered waves for terrestrial paths to distribute radio waves of space propagation path and diffraction. The angular energy spectrum of the scattered waves on such paths is multimodal and causes the periodic nonstationarity of the signals at the outputs of the spaced antennas as the angular position of the narrowly directed antenna of the radio emission source changes. These features take into account the Gaussian model of signals under consideration on the basis of the multimodal angular energy spectrum of scattered waves. Analytical relations, defining conditions for appearance of abnormally large errors in case of receiving signals from radio source with scanning antenna by a direction finder along terrestrial paths, are obtained. It is theoretically proved that it is necessary to compare the phase difference measurement at various bases of the direction finder with a certain threshold in order to detect bearings with abnormally large errors.
