Millimeter Waves: The Evolving Scene

Over the course of the past year, millimeter wave-based (MMW) imaging systems have entered the market, been deployed, and been evaluated in various trial applications. The attractiveness of millimeter wave solutions is that they combine an excellent combination of technology maturity, low cost commercialization, and important performance attributes. These characteristics make them uniquely suited for many important types of concealed weapons and contraband threats, supporting a volume of potential applications. This paper will discuss the state of MMW imaging and likely forward trends.
