SINGLE-POSITION METHOD FOR DETERMINING COORDINATES OF RADIO-FREQUENCY SOURCE LOCATION

摘要

FIELD: radio engineering, communication.;SUBSTANCE: method is based on the energy principle, which consists in measuring (or calculating) the strength of the RFS field and at several space points with known coordinates of their location. The strength of the RFS field is measured on the RCP, and is calculated at the additional point (points). A virtual post (VP), whose coordinates and parameters of its virtual antenna (directional pattern and suspension height) are specified, is proposed as an additional point in the method. When using n VP, they are "placed" not in line with the RCP and are "spaced" from it by latitude and (or) by longitude by several arc minutes. The 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 pularity of radio-frequency sources located in the electromagnetic accessibility zone of the RSC according t the data base and calculated by a certain program both for the RCP and for all given VP.;EFFECT: determination of source location without the use of direction finders and radio receivers with autocorrelators.;5 dwg, 1 tbl
