METHOD OF DETERMINING COORDINATES OF RADIO-FREQUENCY SOURCE Russian patent published in 2016 - IPC G01S5/12 

FIELD: radio engineering, communication.

SUBSTANCE: invention can be used in systems for locating radio-frequency sources. The method of determining coordinates of a radio-frequency source comprises delivering, in the presumed area of the location of a radio-frequency source, direction-finding elements taking into account mutual arrangement thereof on the area and forming a goniometric location system. The goniometric location system is formed by delivering direction-finding stations taking into account spatial requirements of the goniometric system base, consisting of at least two measurement elements which estimate the phase of the received signal. Each carrier is fitted with means for performing the search, detection and determination of parameters of radio-frequency source signals, radio navigation determination of coordinates and data transceiving. One direction-finding station is formed by launching at least two carriers at given delivery coordinates in the area of the location of a radio-frequency source. After mounting into the ground and putting into the working condition using means for the radio navigation determination of coordinates, coordinates of the means for performing the search, detection and determination of parameters of radio-frequency source signals are determined, the values of which are transmitted to a reference radio control station. The means for performing the search, detection and determination of parameters of each direction-finding station perform the frequency search of radio-frequency source signals and measure the phase value upon detection thereof. The phase and frequency values of the received signal of the means for performing the search, detection and determination of parameters of radio-frequency source signals are transmitted to the reference radio control station, where, based on the received data, coordinates of the radio-frequency source relative to the coordinates of the points of delivery of the direction-finding station elements are determined.

EFFECT: high accuracy of determining coordinates of radio-frequency sources located in a hard-to-reach area.
