Hidden microwave active imaging personal security inspection system

Abstract

The invention belongs to the technical field of security inspection, and relates to a hidden microwave active imaging personal security inspection system. All pieces of the conventional microwave active imaging personal security inspection equipment are arranged and used in public and cannot meet the requirements of hidden imaging security inspection. Thus, the invention creatively designs the hidden microwave active imaging system. When an inspected person stays in or passes through an effective imaging region of the hidden imaging system, the inspected person is scanned and imaged by a detection device through a wave-transmitting material; and the system is remotely controlled by an operator or a sensor is used for triggering automatic scanning when detecting that a person comes, so that the imaging security inspection of the person who stays in or passes through a detection range is realized. The hidden microwave active imaging personal security inspection system has various hidden mounting and use modes, including a channel entrance guard hidden mode, an elevator shaft hidden mode, an elevator cage sandwich or outer layer hidden mode, a moving pavement or escalator bilateral stand column / stand plate or door frame hidden mode and a person walk-through hidden mode.

Description

technical field [0001] The invention belongs to the technical field of security inspection, and relates to hidden personnel scanning and imaging security inspection equipment. Background technique [0002] The present invention utilizes micro-waves (such as millimeter waves) that are safe to the human body and can penetrate clothing made of normal materials but will be reflected (scattered) by other higher-density objects to scan and image personnel to obtain the surface of the human body and the objects on the surface of the body. Video, imaging inspection of carry-on items, to achieve the purpose of non-contact "see-through" security inspection of personnel. [0003] At present, human body imaging security inspection equipment in the microwave segment is divided into active and passive imaging equipment, which is different from whether to transmit signal detection. The passive type does not emit detection signals, but only receives natural radiation from people and object...

AI Technical Summary

Problems solved by technology

The passive type can hide the deployment, but the imaging quality is poor. Static imaging can only show a rough outline, and dynamic imaging can only detect the existence of larger objects and cannot identify targets.

The existing microwave active imaging security inspection systems all use millimeter waves, which are designed to conduct public security inspections, and must cooperate with the inspected personnel, and cannot be installed in a concealed manner to conduct secret imaging security inspections of personnel.
