FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering, namely to radio monitoring systems for determining the coordinates of the radio frequency sources location (CRFSL) VHF-microwave ranges of both digital and analog types of communication, information about which is not available in the database (for example, the state radio frequency service). Method is based on an energy principle, which consists in measuring (or calculating) the field strength of a RFS and in several space points with known coordinates of their location. Herewith the field strength of the RFS on a RMP is measured, and in an additional point (points) is calculated. As an additional point in the method, a virtual post (VP) is proposed, coordinates of which and parameters of its virtual antenna (a directional pattern and a suspension height) are specified. When using n VP, they are “placed” not on a straight line with the RCP and “spaced” from it by latitude and (or) by longitude for several angular minutes. Calculation of the strength on the VP is based on the principle of the correlation dependence (CD) of the field strengths, created in a given frequency range by a set of radio frequency sources, located, according to the database, in a zone of electromagnetic accessibility of the RMP and calculated both for RMP and for all given VPs by a certain program. Method is universal both in terms of the types of communication, and the locations of the target RFS – on the Earth's surface or in space. Scanning receiver with an omnidirectional whip antenna is used. In the implementation of this method no expenditures are required for additional equipment. Through the use of virtual posts, without any cost, large statistical base is received allowing to increase the accuracy of determining the coordinates of the RFS location.
EFFECT: achieved technical result is the definition of CRFSL by one radio monitoring post (RMP) and n virtual posts (VP) without the use of direction finders and radio receivers with autocorrelators.
