Abstract: FIELD: radar technology.  
     SUBSTANCE: invention relates to the field of radar, specifically to a method for measuring the azimuth of an aerial target (AT) for a stationary radar station with an azimuthal phased array antenna. In accordance with the proposed method, an N-channel horizontally extended linear phased equidistant antenna array (AA) receives response radio signals from targets in the sector ±( ) degrees from the normal to the AA in the form of quadrature components ( ,  ), arranged like a “fan” of narrow directional patterns equidistant in the working sector  . In this case, the received response radio signals ( ,  ) after intra-pulse processing are subjected to spatial spectral processing using the fast Fourier transform (FFT). Next, Doppler filtering is performed, at the output of which, with the help of threshold processing, marks are formed, while the azimuths of each of the air targets are determined. Then, for each target, the corresponding spectral sample is extracted from the correlation filter field, the inverse fast Fourier transform (IFFT) is performed, and the signal distribution by AA numbers is obtained. Further, the maximum of the spectrum is found by the method for digital generation of the radiation pattern and an azimuth refinement is obtained, after that the output azimuth values of each target are transmitted for further trajectory processing.  
     EFFECT: increased accuracy of measuring the azimuth of targets.
