METHOD FOR DIRECTION FINDING OF RADIO SIGNALS Russian patent published in 2005 - IPC

FIELD: systems of detection and direction finding of signals of radio sources.

SUBSTANCE: reception of radio signals of three-element linear annular equidistant array, transduction of signals by the multichannel receiver with a common local oscillator, production of spectral characteristics of signals simultaneously in all channels, selection of frequency sub-bands occupied by separate signals and evaluation of signal azimuths with the use of formula where - difference spectrum of the K-th radio signal, - reciprocal spectrum, - readouts of channel spectra, K - number of radio channel with signal, n-current number of summation of components of the spectrum of the K-th radio channel, N1 and N2 - values of boundaries of the radio channel converted to the numbers of the spectrum components, i, d - numbers of the elements of antenna array; i - 0,1,2,d - remainder of division of i+1 by 3, all these problems are solved in the method.

EFFECT: enhanced accuracy of processing of information on bearing.
