FIELD: radio equipment.
SUBSTANCE: invention relates to the field of radio equipment, particularly to the millimeter-range antenna arrays for 3D radar. Antenna array comprises M in-series arranged receiving (Rx) linear antenna arrays, each having 2N antenna elements, where M and N are natural numbers, and arranged opposite the said Rx arrays 2M in-series arranged transmitting (Tx) linear antenna arrays, wherein each of the Tx arrays comprising N antenna elements, wherein distance between the antenna elements in each of the Rx and Tx arrays is the same, wherein each of the Rx and Tx arrays is connected to the control circuit corresponding independent port, wherein each of the Rx and Tx arrays is configured to control the phase and amplitude on the control circuit side in order to form the beam pattern with the required characteristics.
EFFECT: technical result is the field of view/resolution maximum ratio with minimum number of transceivers, reduction in the antenna array size due to the surface most efficient use.
