SCANNING APERTURE HYBRID TRANSCEIVING ANTENNA Russian patent published in 2017 - IPC H01Q19/15 

FIELD: radio engineering, communication.

SUBSTANCE: scanning aperture hybrid transceiving antenna contains a parabolic reflector for the radar, in the focal plane of which linear array of emitters is located from N=2ⁿ emitters, the channels of which are input and output, connected through appropriate 2ⁿ output channels the input channels will Butler matrix and through 2ⁿ input channels will Butler matrix output channels for transmission. The Butler matrix outputs are connected to the digital antenna array, at the output of which m foster digital rays of the hybrid antenna are formed, and the hybrid antenna input for transmission through the breeder and the block of 2ⁿ phase shifters is connected with the corresponding 2ⁿ input channels of the Butler matrix for transmission. The block of phase shifters is controlled by radar signals.

EFFECT: reducing the target acquisition time by radar, increasing the accuracy of its tracking by the elevation angle and the heading angle, when the step of the discrete scan is much smaller than the directivity diagram width DD, and increasing the noise immunity of radar through the use of additional m digital receiving DD.
