Abstract

The embodiment of the invention discloses a human body characteristic measuring method, a human body security detecting method and an FMCW radar-millimeter wave security detecting device. The human body characteristic measurement method using an FMCW radar comprises the steps that a plurality of mannequins and classifications are provided; the FMCW radar is used for emitting electromagnetic wavestoward the mannequins separately and collecting echo data to obtain an echo data-human body shape classification corresponding relation; the FMCW radar is used for emitting electromagnetic waves toward a to-be-tested human body and collecting echo data, and the to-be-tested human body is determined to be one of the various human body shape classifications based on the collected echo data-human body shape classification corresponding relation.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of security inspection, and in particular, to a method for measuring human characteristics, a method for human body security inspection, and an FMCW radar-millimeter wave security inspection device. Background technique [0002] At present, the form of counter-terrorism at home and abroad is becoming more and more serious. Terrorists use concealed methods to carry guns, knives, explosives, drugs and other dangerous goods, posing a great threat to space safety. The human body security inspection technology in special occasions such as airports and railway stations has been highly valued by the transportation management departments of various countries. [0003] In the prior art, in the process of using millimeter waves to check suspicious objects hidden in the human body, operators need to identify them; in addition, because different people have different body shapes, the image identificatio...
