Probe device and control method for millimeter wave human concealed weapon monitoring

Abstract

The invention discloses a millimeter wave probe device and a millimeter wave control method for monitoring a weapon hidden on a human body. A millimeter wave probe consists of a millimeter wave antenna, a millimeter wave amplifier and a millimeter wave detector which work at the millimeter wave frequency, a direct-current amplifier, a signal processing unit and a power supply unit which work at low frequency, and a personal computer (PC). When the millimeter wave probe performs monitoring, the human body advances towards the millimeter wave probe, the millimeter wave probe outputs a monitoring signal to the PC from the moment when the human body enters a millimeter wave probe monitored area to the moment when the human body leaves the millimeter wave probe monitored area; if the weapon is not hidden on the human body, the monitoring signal output by the millimeter wave probe to the PC is an approximate bell-shaped pulse signal, and the PC makes judgment that the weapon is not hidden on the human body and sends a release command; if the weapon is hidden on the human body, the monitoring signal output by the millimeter wave probe to the PC is a non bell-shaped pulse signal which has the characteristic that the top of the signal is sunk, and the PC makes judgment that the weapon is hidden on the human body and sends an alarm command.

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment, and in particular relates to a probe device and a control method for monitoring a millimeter-wave human concealed weapon. Background technique [0002] Existing monitoring technology has a long history. It has been widely used in the fields of security and anti-terrorism.
