METHOD FOR DETERMINING LOCATION OF RADIO SOURCE WITH PERIODIC STRUCTURE OF SIGNAL AND ROTATING DIRECTED ANTENNA

FIELD: radio engineering.SUBSTANCE: invention relates to the field of radio engineering and can be used in systems of radio technical control and secondary radar. Specified result is achieved due to the sequential reception of radio sources signals from Nsuccessively irradiated repeaters with known coordinates, determining the characteristics of the radio sources: the structure of the signal for one radiation period and the period of rotation of the directional antenna, selecting a "reference" repeater, extrapolating the signals received from the "reference" repeater based on the signal structure data for one radiation period and the rotation period of the directional antenna, measurement of primary spatial information parameters (PSIP) of the first group, measurement of the PSIP of the second group, representing the time delays between the extrapolated signals of the "reference" repeater and the received signals of the successively irradiated repeaters, the measurement of the third group PSIP, representing the duration of the time intervals between the instant of the position of the rotating directional antenna of the radio source corresponding to the direction of the main lobe of its directional pattern to the "reference" repeater, and the moment of the position of the rotating directional radio source antenna corresponding to the direction of the main lobe of its directional pattern to the remaining successively irradiated repeaters, the formation of the primary coordinates of the first group, the formation of the corresponding primary coordinates of the second group by the measured PSIP - the difference in distances between the radio source and the "reference" repeater and between the radio source and each remaining successively irradiated repeater, the formation of the corresponding primary coordinates of the third group from the measured PSIPs are the azimuthal viewing angles in the plane of the local horizon of the topocentric coordinate system, associated with the location of the radio source, a pair of objects composed of a "reference" repeater and each remaining successively irradiated repeater, together with forming the first group of formation position surfaces for the second and third groups of primary coordinates, the corresponding second and third groups of position surfaces, together with the formation of the first group of lines of the position of formation of possible groups of position lines as the geometric locus of the points of inters
