METHOD FOR DETERMINING THE SOURCE OF RADIO EMISSIONS COORDINATE FROM THE AIRCRAFT Russian patent published in 2017 - IPC G01S1/08 G01S5/04 

FIELD: radio engineering, communication.

SUBSTANCE: method is based on measuring three orthogonal components of the electric field strength vector in the E_{ac x}, E_{ac y}, E_{ac z} spaces; forming of an auxiliary plane passing through the center by the airborne antenna system (AAS) of aircraft (AC) with coordinates (x_ac, y_ac, z_ac) and perpendicular to the electric field strength vector transformed into a topocentric coordinate system, which is determined by three orthogonal components E_{t x}, E_{t y}, E_{t z}; determining the RES position line as the intersection line of each of the auxiliary planes with the Earth's surface; and calculating the coordinates of radio emission sources (RES) at the point of intersection of the RES position lines formulated in process of AC movement.

EFFECT: increasing the accuracy of determining the coordinates of radio emission sources by providing polarization matching between the receiving airborne antenna system and the incoming electromagnetic wave field.
