摘要

Embodiments of the present disclosure provide a sparse multiple-input multiple-output array arrangement for active millimeter wave security inspection imaging, a human body security inspection apparatus, and a human body security inspection method. The sparse multiple-input multiple-output array arrangement includes two sets of transmitting antennas and a set of receiving antennas. The two sets of transmitting antennas include first and second sets of transmitting antennas, each set of transmitting antennas including a plurality of transmitting antennas arranged along a first direction. The set of receiving antennas includes a plurality of receiving antennas also arranged along the first direction and coplanar with the first and second sets of transmitting antennas, and is located between the first and second sets of transmitting antennas in a second direction perpendicular to the first direction.
