DIGITAL SCANNING RECEIVING ANTENNA ARRAY FOR RADAR STATION Russian patent published in 2016 - IPC H01Q3/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in radar systems. Device comprises an antenna array of N receiving antenna modules, digitisation device receiving signals, a digital device for production of coefficients for formation of amplitude-phase distribution in aperture of antenna at each of scanning beams, apparatus for digital generation of M scanning beam patterns, each receiving antenna module additionally contains a digital device for generating beam pattern, digital device for production of weight coefficients is configured to generate in aperture of digital receiving antenna array of N amplitude-phase distributions type sinU/U so, that in the far zone each receiving element corresponds to beam pattern, on shape close to table-like.

EFFECT: technical result is simpler device and larger scanning sector with a constant amplitude of main lobe of beam pattern of antenna array.
