METHOD FOR DETERMINING LOCATION OF A QUASI-CONTINUOUS BROADBAND SOURCE OF RADIO-EMISSION BY MOBILE COMPLEX OF RADIO-TECHNICAL SUPERVISION Russian patent published in 2018 - IPC G01S5/06 

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to radio engineering and can be used in the development of multi-position complexes of radio technical supervision. Method consists in: receiving a quasi-continuous broadband signal by antenna array at each receiving position of the radio technical supervision complex, forming intervals of observation with duration t_sup., on which the correlation matrix of signals R_xx(m) of the input realization of a quasi-continuous wideband signal is calculated according to a certain formula, calculating a difference correlation matrix of signals ΔR_xx(m) = R_xx(m)-R_xx(m+l), calculating the determinant of the difference correlation matrix with the subsequent formation and normalization of dependence for constructing position lines; calculating the correlation function of dependence by the corresponding formula, determining the path difference for each position with respect to the maximum of the enveloping mutual correlation function by the system of mutual correlation processing, estimating the coordinates of the source of quasi-continuous broadband signal by the time difference method on the basis of analysis of the time dependence of the determinant of the difference-correlation matrixes of the signals generated in the elements of the antenna arrays at receiving points of the radio technical supervision complex.

EFFECT: achieved technical result of the invention consists in improved accuracy of positioning the sources of a quasi-continuous wideband signal by a complex of radio-technical supervision and reduced time required to locate sources of radio emission.
