In response to the ever-increasing global threat of terrorist
attacks, the personal screening industry has been growing at a
rapid rate. Many methods have been developed for detecting
concealed weapons and explosives on the human body. In this
important new book, the authors discuss their experiences over the
last decade designing and testing microwave and millimetre wave
detection and screening systems. It includes examples of actual
devices that they have built and tested, along with test results
that were obtained in realistic scenarios. The book focuses on the
development of non-imaging detection systems, which are similar to
radar. These systems do not form a conventional image of the scene
and the person(s) being screened. Instead, the sensors detect and
analyze the effect that the body, and any concealed objects, has on
a transmitted waveform. These systems allow remote detection of
both metallic and dielectric devices concealed on the human body in
both indoor and outdoor environments. The book discusses a number
of sensor types, including active millimetre wave sensors using the
direct detection and the heterodyne approach, active microwave
sensors for CNR-based object detection, passive millimetre wave
sensors, and the role of shielding effects in operating non-imaging
MM-wave sensors. The goal of this book is to systemize the test
results obtained by the authors, helping specialists to develop
improved screening systems in the future. Another goal is to show
how the use of non-imaging systems can reduce the cost of the
screening process.
