FIELD: radio engineering and communications.
SUBSTANCE: invention relates to the field of radio engineering, namely to radio monitoring systems for determining the location of radio-frequency sources (RFS) microwaves – ultrashort waves of both digital and analog communication types,the information about them is not available in the database (for example, the state radio frequency service or the state service of supervision of communication). At the heart of the method lies the energy principle, which consists in measuring (or calculating) the strength of the RFS field at several space points with known coordinates of their location. Herewith, the RFS field intensity on the RKP is measured, and at the additional point (points) it is calculated. In the method, a virtual post (VP) is proposed as an additional point, where the coordinates are given. When several VP are used, they are "placed" not on one straight line with the RKP and removed from it for several angular minutes. Herewith, the VP are "positioned" around the beam from the RKP to the desired RFS so that the distance between them increases, and between them and the azimuth beam contracts, when it moves away from the RKP. Calculation of the VP intensity required for determine the coordinates of the location of the desired RFS is based on the principle of the space points correlation dependence (CD) upon the field strength created in a given frequency range by each of the set of basic sources of radio emission located, according to the database, in the electromagnetic accessibility zone of the RKP and calculated for both the RKP and for all given VP of a certain program, for example, under the PIAR program of the Yaroslavl State University.
EFFECT: improving the accuracy of determining the coordinates of the location of the RFS.
