Abstract
The invention discloses an active millimeter wave contraband detecting instrument. The detecting instrument comprises a case assembly, a millimeter wave emitting assembly, a millimeter wave receiving assembly, a signal processing circuit and a power supply. The case assembly comprises an LCD provided with a touch screen and mounted on a main casing, a battery charging socket, a power supply switch and an alarm lamp. The millimeter wave emitting and receiving assemblies are mounted above a separator plate. The millimeter wave emitting and receiving assemblies comprise a millimeter wave signal source, an emitting horn antenna and a corresponding lens, a receiving antenna and a corresponding lens, a detector, a low-noise amplifier and a video amplifier. The signal processing circuit employs a multichannel pulse amplitude analyzer provided with a 32-bit embedded microprocessor. The power supply employs a chargeable battery. The invention employs a novel contraband detection method, the active millimeter wave contraband detecting instrument employs an active millimeter wave detection manner, a common detection method by the use of radioactive elements (gamma-rays or x-rays) is replaced, and the novel detection method does no harm to human bodies and meets environmental protection requirements. The detecting instrument is simple in structure and low in cost, and the effective distance for the detection can be adjusted through changing the length of the antennas, the beam width, the size of the lenses, or the angle between the two antennas.
