ALERT Researchers Awarded Patent
May 29, 2019
ALERT researchers, Professor Carey Rappaport and Professor Jose Martinez-Lorenzo of Northeastern University were awarded a patent for an “On-the-Move Millimeter Wave Interrogation System with a Hallway of Multiple Transmitters and Receivers” on May 21, 2019.
In conventional screening systems that use radar imaging for surveillance and detection purposes, an object of interest may be illuminated (using millimeter wave) and the scattered field measured and processed to reconstruct a feature of the object. These systems may generate an image that profiles a detectable shape, outline and/or movement of an object or subject; however, conventional radar systems, such as a portal-based system, constrains a subject from movement. Professor Rappaport and Professor Martinez-Lorenzo’s patented solution allows for screening an unconstrained subject, meaning an individual could be scanned for foreign objects attached to their bodies (such as explosives and weapons hidden under clothing) as they moved through a hallway of transmitters and receivers. Such a system could lead to faster and more accurate screening of individuals as they make their way through security checkpoints.
