technical field [0001] The invention relates to the field of millimeter-wave beam-focusing random radiation cavity antennas, in particular to a millimeter-wave frequency polarized dual-random multi-port beamforming antenna. Background technique [0002] The existing millimeter-wave spotlight random radiation cavity antenna mainly uses the randomly changing mechanical structure in the cavity or the random control surface designed by metamaterial technology to change the excitation amplitude-phase characteristics or modulation amplitude-phase characteristics of the antenna under different operating frequencies. In this way, low-correlation random radiation patterns can be generated at different operating frequencies; these random radiation patterns will encode the imaging plane where the target is located, and the encoded imaging plane can be used as a reference detection mode in calculating correlation imaging.
