Current imaging technology for concealed weapon detection in the millimeter-wave (mm-
wave) and terahertz ranges is traditionally limited to a single type of sensor. In this paper, a …

A real-time image processing algorithm, using a GPU with NVIDIA's CUDA technology, for a
3-D through-clothes detection radar in the THz band has been developed. Traditional CPU …

Recent research in the millimeter-and submillimeter-wave frequency bands has driven the
maturity of its technologies to a level where integrated and commercial radiofrequency …

Increasing threats of terrorism and contraband smuggling have led to a growing interest in
millimeter wave/THz security sensors. Recently, systems combining active and passive …
