Contraband detector and contraband detection method

Abstract

The invention discloses a contraband detector and a contraband detection method. The contraband detector comprises a signal generator, a circulator, an antenna, a wave detector, a filter, an amplifier, an analog-digital converter and a processor, wherein the signal generator, the circulator, the wave detector, the filter, the amplifier, the analog-digital converter and the processor are sequentially connected; and the antenna is connected with the circulator. According to the contraband detector, a millimeter wave source is adopted as a signal source of a to-be-detected sample, the material type of a to-be-detected target is determined in an inversion manner through collecting and processing an electromagnetic signal with an eigen value in an interacting echo signal of a millimeter wave and the to-be-detected sample, and whether the to-be-detected sample is a suspected object or not is further judged. The contraband detector has the advantages of being simple in structure and convenient to carry, and can be widely applied to transportation hubs such as an immigration inspection port, a railway station and an airport.

Description

technical field [0001] The invention relates to the field of contraband detection, in particular to a contraband detector and a contraband detection method. Background technique [0002] With the development of society and the progress of civilization, people's requirements for public safety and drug control are increasing day by day. There are some similar devices in public places now, such as security detectors, but their device structures are complex and have radioactive sources; Although the detector (model EX-DETECTXD-2) has a simple structure, it needs to manually add reagents, so the repeated detection time is relatively long, which greatly affects the detection efficiency. [0003] Therefore, how to provide a contraband detection device with simple structure, no radioactive source, and convenient and quick use has become an urgent problem in this field. Contents of the invention [0004] The purpose of the present invention is to provide a contraband detector and...
