In response to the urgent demand for efficient, safe, and speedy imaging in remote security screening applications, a new sub-terahertz security body scanner has been developed. Integration of innovative THz sensing technique and advanced IMPATT-diode-based signal-generating technology resulted in a cost-effective cutting-edge system capable of real-time visualization of the threats hidden under the clothes of people. This paper introduces the new 100-GHz security scanner and presents the test results which demonstrate that it can perform through-garment detection at standoff ranges of 3–6 m with respective lateral resolution of 3–6 cm. The depth of the field of the system has been determined experimentally to be approximately 30 cm.
