DEVICE FOR DETECTING NON-METALLIC OBJECTS LOCATED ON A HUMAN SUBJECT

摘要

The invention concerns devices for detecting objects concealed on human subjects. These devices are particularly dedicated to the surveillance and security of airport areas and transport aircraft. Currently, existing devices rely either on detection using X-rays or on microwave imaging. In the first case, the system can prove to be dangerous to human beings and in the second case, the device poses ethical problems. The invention provides a device whose operation relies on the polarized microwave reflective properties of suspicious objects to be detected. This device can be portable or installed on security portals. This technique has a simple design, is inexpensive, does not require a high computing power and is very well adapted to objets to be detected. The complete measurement is extremely fast and does not require a sophisticated measuring instrument.
