Abstract
An aimed or aiming firearm can be detected before it is able to shoot. Wideband radar signals can be used to identify the barrel of a firearm when the radar antenna and barrel are aiming at or near each other. Signal processing correlates reflected signals to the characteristics of specific firearms of interest, and alerts the user when someone is pointing such a firearm at them. Modern wideband radar systems with fast signal processing speed can enable real-time detection of firearm threats in crowded and cluttered areas before they shoot, which has never before been possible. Related systems, apparatus, methods, and articles are also described.
