Embodiment Construction
[0018] In order to describe the technical solution disclosed in the present invention in detail, the technical solution of the present invention will be further introduced below in combination with specific embodiments and accompanying drawings.
[0019] The invention discloses an all-digital beamforming antenna array with a non-reciprocal sending and receiving pattern and a realization method thereof. Digital transceiver beamforming system architecture, and the number of receiving or transmitting channels is reduced from the original M×N to P×Q (P
[0020] Specifically, such as figure 1 As shown, an all-digital beamforming antenna array with a non-reciprocal transmit-receive pattern includes M×N transmit-receive channel units arranged periodically in a rectangular grid. The number of sub-units one 2 is a part of the array 1 . Unit channel 4 in subunit 1 has both transmitting and receiving functions. The transmitting part of these channels is connected to a digital ...
