Security inspection equipment and control method thereof

Abstract

The invention provides security inspection equipment and a control method thereof. The security inspection equipment comprises a bottom plate, two-dimensional multiple-input multi-output transceivingarray panel, at least one two-dimensional multiple-input multiple-output transceiving subarray, a control circuit, a signal processing device and a display device. The bottom plate is used for bearingan object to be inspected; the two-dimensional multiple-input multi-output transceiving array panel is arranged on the bottom plate and is parallel to the bottom plate; each two-dimensional multiple-input multiple-output transceiving subarray includes a plurality of transmitting antennas and a plurality of receiving antennas, the transmitting antennas and the receiving antennas are distributed toenable equivalent phase centers to be arranged in a two-dimensional array; the control circuit is used for controlling the transmitting antennas to transmit detection signals in a form of electromagnetic waves to the object to be inspected according to a preset sequence and controlling the receiving antennas to receive echo signals from the object to be inspected. The signal processing device isused for reestablishing an image of the object to be inspected according to the received echo signals. The display device is sued for displaying the reestablished image of the object to be inspected.

Description

technical field [0001] The present disclosure relates to the technical field of security detection, and in particular to a security detection device and a control method thereof. Background technique [0002] At present, the situation of anti-terrorism at home and abroad is becoming more and more serious. Terrorists use hidden methods to carry guns, knives, explosives, drugs and other dangerous goods with them, which poses a great threat to public safety.
