LLNL researchers have developed a lightweight drone-based GPR array that when flown over a surface with laid and/or buried objects could image the field of view and be able to detect targets and discriminate them from clutter. The imaging method employs a modified multi-static architecture to provide the highest signal to noise with the lowest system weight, making it…

GuardDog technology uses ultra-wideband (UWB) impulse sensors (also known as micropower impulse radar or MIR), optional global positioning systems (GPS), local signal processing, and user-selectable (power and bandwidth) radio frequency (RF) communication transceivers. UWB sensors emit and detect very-low-amplitude and short-voltage impulses for detecting returning radar signals. By employing…
