Design of human body scanner based on 4–11 GHz ultrawideband technique for airport security applications

Currently, the airport became one of the very vital and should have a very high level of security. The main problem that arises is how to optimize airport security systems that already exist so as to improve the safety and comfort of passengers planes. In this study we propose an ultrawideband imaging for scanning the human body to detect the presence of weapons and weapons concealment locations by prospective passengers in the body. Ultrawideband technique has advantages compared to metal detector in terms of its ability to produce images sharp weapons, and its size, shape and exact position of the sharp weapon. From the initial study conducted shows that the candidate body scanner system on this plane capable of detecting hazardous metal beneath the cloth with an acceptable error rate.
