METHOD OF DETERMINING COORDINATES OF RADIO-FREQUENCY SOURCE FROM AIRCRAFT USING TRI-ORTHOGONAL DIPOLE ANTENNA SYSTEM Russian patent published in 2024 - IPC G01S1/08 G01S5/02 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended for use in radio monitoring systems when solving the problem of hidden determination of coordinates of a radio-frequency source (RFS) from an aircraft (AC). Result is achieved by placing a tri-orthogonal dipole antenna system (TODAS) on a space-movable AC; using TODAS, measuring orthogonal components E_x1, E_y1, E_z1, Ex₂, E_y2, E_z2, E_x3, E_y3, E_z3 and E_x4, E_y4, E_z4 vectors of electric field intensity at moments of time t₁, t₂, t₃ and t₄, determining orientation of vectors in space, constructing of auxiliary planes Ω_E1, Ω_E2, Ω_E3 and Ω_E4, constructing lines of position of the RFS l₁ and l₂ and calculating the coordinates of the RFS at the point of intersection of the position lines of the RFS l₁ and l₂.

EFFECT: high accuracy of determining coordinates of a radio-frequency source based on the use of a space-displacing AC equipped with a TODAS.
