Abstract

A close-range high-resolution radiometric imaging system is described that demonstrates a capability to see through clothing and provide high resolution images of concealed weapons. The radiometer receiver is lens-fed and operates in W-band. It uses a system of linear actuators to rapidly scan the receiver at a range of approximately 1 meter from the subject. The images are of a high quality and are believed to be the best that have been published to date in the open literature. They represent a major step forward in the application of passive millimeter-wave technology to commercial applications such as security screening for concealed weapons detection. The paper describes the design of the experimental imaging system and includes images that demonstrate a state-of-the-art weapons detection technology.
