METHOD FOR LOCATION OF SOURCE OF RADIO-FREQUENCY RADIATIONS Russian patent published in 2005 - IPC

FIELD: radio engineering, in particular, passive radio control systems.

SUBSTANCE: the method consists in measurement of the direction to the source of radio-frequency radiations, estimation of relative time delay with a subsequent computation of the coordinates of the source of radio-frequency radiations as a point of intersection of the line of direction to the source and the hyperbolis line of the position, all the measurements are taken at one receiving point, the relative time delay is determined by estimation of the discrepancy of the time of signal arrival from the source relative to the reference time scale formed on the basis of estimation of time structure of the signal source, whose position is supposed to be known, and the coordinates of the source of radio-frequency radiations are computed as the point of intersection of the line of direction to the source and the hyperbolic line of the position determined on the basis of comparison of the estimations of the discrepancy of the time of arrival of signals in time from the sources with the known and estimated location functioning in a single system of synchronization by digital (discrete) types of signals.

EFFECT: provided determination of the coordinates of the sources of USW-SHF radio-frequency radiation ranges using digital (discrete) types of signals from one point of radio control.
