METHOD AND DEVICE FOR DETERMINING COORDINATES OF RADIO EMISSION SOURCES Russian patent published in 2019 - IPC G01S13/46 

FIELD: radio engineering and communications.

SUBSTANCE: inventions relate to radio engineering and can be used to determine the location of radio emission sources (RES) of a flight-lifting device (FLD) in a goniometric way. Technical result is achieved by excluding from calculations of knowingly false bearings by calculation for each of their combination ψ_j m-th local zone of angular distances on sphere δ_j between obtained bearings and previously found coordinates of RES, determination of bearing filtration threshold level σ_j, equal to mean-square deviation of bearing set ψ_j of obtained angular distances δ_j. Using σ_j bearings can be dropped, angular distances on sphere of which δ_j it is exceeded. Device for determining coordinates of radio-frequency sources implementing the method includes a two-channel phase interferometer, ten computers, eight memory units, a radio navigator, device for angular orientation of FLD, comparator unit, decision making unit, two units for calculating coordinates, unit for calculating threshold levels, bearing selector, eleven input setting buses and output bus, connected to each other in a certain manner.

EFFECT: high accuracy of determining coordinates of RES.
