Abstract: A portable security inspection device based on millimetre wave imaging comprising a hand-held body, wherein the hand-held body is provided with a millimetre-wave transmitting circuit for generating a millimetre-wave transmitting signal, a millimetre-wave array antenna for transmitting the millimetre-wave transmitting signal to a detected object and for receiving an echo signal reflected by the detected object, and a millimetre-wave receiving circuit for processing the echo signal and converting the echo signal into image data of the detected object.

Abstract: A close range microwave imaging method and system is provided. The method comprises: controlling a linear antenna array consisting of a preset number of antennas to rotate along a preset arc trajectory so as to scan a target region; controlling the linear antenna array to acquire a preset number of echo data at azimuthal positions on the arc trajectory and to send an echo data set constituted by the preset number of echo data to a signal processing device until the linear antenna array completes the acquisition of echo data at preset azimuthal positions on the arc trajectory; and controlling, every time the signal processing device receives the echo data set, the signal processing device to perform imaging processing on the echo data set.

Abstract: The present disclosure relates to a monitoring method, a monitoring system and a control device for a human-body security-inspection device. The monitoring method includes: collecting operation parameters of preset monitoring points in target circuit modules of the human-body security-inspection device; obtaining parameter ranges according to module identifiers of the target circuit modules and monitoring-point identifiers of the preset monitoring points, wherein the parameter ranges are associated with the module identifiers and the monitoring-point identifiers respectively; determining whether the operation parameters are in the parameter ranges respectively, and then determining location information of a fault point according to the module identifiers and the monitoring-point identifiers if any of the operation parameters is not in a corresponding parameter range.
