Millimeter wave imaging equipment, security inspection equipment and security inspection method

The invention provides millimeter wave imaging equipment, security inspection equipment and a security inspection method. The millimeter wave imaging device comprises: a first millimeter wave transmit-receive array comprising a row of first millimeter wave transmitting antennas and a row of first millimeter wave receiving antennas; and the second millimeter wave transceiving array comprises a row of second millimeter wave transmitting antennas and a row of second millimeter wave receiving antennas. The first millimeter wave transceiving array and the second millimeter wave transceiving array are respectively configured to transmit and receive millimeter waves to construct a first holographic image and a second holographic image of an inspected object. The millimeter wave imaging device is further configured such that the second millimeter wave receiving antenna receives the millimeter waves of the first millimeter wave transmitting antenna to form a first transmission image, or the first millimeter wave recei
