摘要：

Passive millimetre-wave imaging provides the capability to detect objects concealed beneath clothing. In the past, this has been accomplished successfully outdoors, using the cold sky illumination to provide the majority of the scene contrast. However, many applications, such as airport security scanning, require a technology that can operate in an indoor environment. This paper describes work undertaken to develop a safe and effective illumination source for indoor millimetre-wave imaging. Results from a prototype real-time indoor millimetre-wave security scanner are presented, clearly showing hidden weapons, both metal and ceramic, and other objects.
