METHOD FOR FORMING THE DIAGRAMS OF THE DIRECTION OF A RECEIVING RING DIGITAL PHASE ANTENNA ARRAY Russian patent published in 2018 - IPC H01Q3/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna technology, namely antenna systems with a hardware-generated beam pattern and electron beam control, and can be used in mobile and fixed communications. Amplitude A_n and phase ϕ_n the coefficients of the formed radiation pattern are calculated by a special numerical algorithm that simultaneously optimizes two functional: minimizes the root-mean-square deviation of the ZFAR directivity diagram from the theoretical optimal, taking into account the mutual influence of the antenna elements (for example, from a common-mode diode mathematically shifted to the required scan angle ϕ_c, whose side lobes are "artificially" reduced to the required level), and maximizes the signal-to-noise ratio of the entire receiver system, which is responsible for its sensitivity.

EFFECT: formation of the scanning radiation patterns of the receiving system with the required level of side lobes and the minimum value of the sensitivity level.
