A METHOD FOR SINGLE-POSITION DETERMINATION OF SPATIAL COORDINATES OF RADIO SOURCE Russian patent published in 2021 - IPC G01S5/12 G01S3/74 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering, namely to passive radio monitoring systems, and can be used in systems for locating radio-emitting means. In the claimed method for single-position determination of the spatial coordinates of the radio emission source (RES), a signal reception and processing point (SRPP) is placed in the RES radiation reception zone, including 1, 2 and 3 receiving channels, and the coordinate binding of the receiving channels is carried out. Next, the values of the phases of the received RES radiation are measured by each receiving channel and transmit them and their location coordinates to the SRPP. Then, the coordinates of the center of the circle inscribed in the triangle formed by the points of location 1, 2, and 3 of the receiving channels are determined, and their values are transmitted to the SRPP. The fourth receiving channel is installed in the calculated coordinates, the phase of the received RES radiation is measured in it and its values are transmitted to the SRPP. After that, according to the values of the measured phases 1, 2, 3 and 4 by the receiving channels of the received RES radiation, their location coordinates and, under a priori given condition of the presence of a spherical shape of the RES radiation wavefront, the coordinates of the RES location are calculated on the SRPP.

EFFECT: technical result is the reduction of direction finding points for the location of the RES.
