DICHOTOMOUS MULTIPLICATIVE DIFFERENCE-RELATIVE METHOD FOR MOBILE DETERMINATION OF COORDINATES OF POSITION OF RADIO-FREQUENCY SOURCE Russian patent published in 2015 - IPC G01S5/02 

Abstract RU 2558639 C2

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio monitoring systems for determining the position of radio-frequency sources. The method is based on using measurements by a mobile radio monitoring station of signal strength values at each of assigned frequencies at three points in space and conversion into paired multiplicative difference of inverse ratios thereof and ratios of distances from measurement points to the radio-frequency source. A dichotomous method is employed to process the multiplicative differences of said ratios. The method is based on the principle of consecutive determination of parameters of the position of the radio-frequency source: latitude Xi, longitude Yi and altitude Zi based on the criterion of searching for the minimum of the differences of ratios of the distance of the position of the radio-frequency source to measurement points which are not located on the same line, and corresponding inverse ratios of the measured signal strength values.

EFFECT: determining spatial coordinates of the position of fixed radio-frequency sources with one mobile radio monitoring station.
