METHOD OF DETERMINING SPATIAL COORDINATES OF RADIO-FREQUENCY SOURCE Russian patent published in 2016 - IPC G01S5/12 

FIELD: radio engineering, communication.

SUBSTANCE: method employs a multi-position system comprising at least two spaced-apart signal processing and receiving stations (SPRS) and a radio-frequency source spatial parameter determining station (SPDS) linked thereto. The SPRS each comprise three receiving channels (points) randomly arranged relative to each other, each performing the estimation of the phase of the received wave. The SPRS have coordinate referencing of each receiving channel (point) in a Cartesian coordinate system. The values of the coordinates of the receiving points (channels) and the estimate values of the phase of arrival of a wave in each channel are sent to the SPDS which, using the measured phase values of the radio-frequency source, construct phase planes of the received field with each SPRS, and coordinates of the radio-frequency source are determined from coordinates of the middle of the minimum section connecting straight normal lines to the said phase planes.

EFFECT: eliminating limitations on the mutual spatial arrangement of receiving channels of direction-finding stations.
