The U.S. Army Research Laboratory (ARL) has developed a framework to study how easily ultraviolet communication (UVC) systems can be detected. Although the work focuses on longer-term applications, it could ultimately enable more secure network connectivity for soldiers in adversarial environments.
Deep UV wavelengths have propagation characteristics that allow for a non-line-of-sight (NLOS) optical link that can make deep-UV communications harder for an adversary to detect. “The increased atmospheric absorption of deep-UV wavelengths implies that UV communication, or UVC, has a natural low probability of detection, or LPD, characteristic,” ARL researcher Robert Drost said. “In order to fully take advantage of this…READ MORE
