FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering, particularly to radio monitoring systems for determining the position of pulsed radio-frequency sources. Method is based on the use of measurements of the signal arrival times to four stationary radio control stations, while calculating the propagation time differences of signals from the RES to stations based on the measured arrival times of the signals, form a Cayley-Menger determinant of dimension 6×6, which vanishes for any five points of Euclidean space, and the numerical solution of this determinant gives values of the distances from the source to the stations and on the basis of the proportional correspondence of the ratios of distances from the station to the RES and the corresponding ratios of the pulse signal delay values, all combinations of the multiplicative differences of these ratios are obtained, processing of relations multiplicative differences is carried out by a dichotomous method or methods of accelerated descent, which is based on the principle of sequential determination of the RES location parameters: latitude – Xi, longitude – Yi and altitude – Zi based on the criterion of the minimum differences in the ratio of the distance of the location of the RES to the stations of radio monitoring, not located on the same line, and the corresponding ratios of the signal delays measured at the stations.
EFFECT: simplification by determining the spatial coordinates of the location of radio emission sources (RES) by four stationary stations without attracting the position lines equations.
