Handmade explosive devices (HEDs) used by terrorists are among the most threatening methods for the army, police and other law enforcement officers. TRV HPEM system has designed to disable HED threats triggered by electronic sensors such as timers, clocks, PIR detectors, motion sensors and wireless remote control. The HPEM system consists of a remotely controlled unmanned vehicle with a MARX generator and a UWB antenna as a load. System generates a very large electric field and spread it with the antenna, so this electric field affects the electronics involved in the HED threats.
