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.

Portable security inspection device based on millimetre wave imaging

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.

Close range microwave imaging method and system

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. Therefore, the present disclosure can quickly locate the position of the fault point, thus it is convenient in the maintenance and test work, and improve the efficiency of the maintenance and test work.
