Patent ID: 11125906

Abstract:
A disclosed system includes a support frame including a plurality of surfaces, a millimeter-wave transmission link that generates a millimeter-wave transmission signal, a plurality of millimeter-wave array antennas, a millimeter-wave reception link, and an image processing device. The millimeter-wave array antennas are disposed on different surfaces of the support frame, and transmit millimeter-wave transmission signals from different angles to a to-be-detected object and receive echo signals reflected from the to-be-detected object. By providing the millimeter-wave array antennas on each of the plurality of surfaces of the support frame, and transmitting millimeter-wave transmission signals from different angles to a to-be-detected object and receiving echo signals reflected from different angles of the to-be-detected object, a three-dimensional image of the to-be-detected object can be established, thereby achieving omni-directional detection of the to-be-detected object. The system can detect human and objects at the same time, and is convenient, quick and highly accurate.
