Abstract

The invention relates to a virtual-axis millimeter-wave human body security check system. The system comprises a virtual-axis guide rail unit, a scanning unit, a scanning driving unit, a data processing unit and a display unit, wherein the virtual-axis guide rail unit comprises a first circular-arc-shaped guide rail; the scanning unit comprises a first group of millimeter-wave antenna arrays and a first millimeter-wave transceiver; the scanning driving unit is used for driving the first group of millimeter-wave antenna arrays to scan in a reciprocating virtual-axis circular-arc-shaped locus on the first circular-arc-shaped guide rail; the data processing unit is used for processing a detection signal from the scanning unit to form a human body image to be detected; the display unit is used for displaying the at least one human body image to be detected. In the human body security check system disclosed by the invention, a virtual-axis scanning way is used, the motion load does not need to be reduced, and the rotational inertia is reduced, so that the scanning speed is increased. The system is small in occupied space, and a single / double-module security check system can be assembled more flexibly according to the size of a practical space and the checked amount.
