SINGLE-POSITION MULTIPLICATIVE DIFFERENTIAL-RELATIVE METHOD TO DETERMINE LOCATION COORDINATES OF RADIO RADIATION SOURCES Russian patent published in 2018 - IPC G01S5/02 

Abstract RU 2643780 C1

FIELD: radio engineering, communication.

SUBSTANCE: method is based on the energy principle, which consists in measuring (or calculating) the RFS intensity field and at several space points with the known coordinates of its location. The RFS field intensity is measured on the RCP, and at the additional point (points) it is calculated. The virtual post (VP) is proposed as the additional point, the coordinates and parameters of its virtual antenna (directional diagram and suspension height) are specified. When using of n VP it is placed not in line with the RCP and is "spaced" from it by latitude and (or) by longitude at several arc minutes. The intensity calculation at the VP is based on the principle of the correlation dependence (CD) of the field intensities, created by the multiple radio-frequency sources within the given frequency range, located according to the data base in the RCP electromagnetic accessibility area and calculated by the certain program both for the RCP and for all given VP.

EFFECT: determination of coordinates without using the location finders and radio receivers with autocorrelators.
