Method and apparatus for protecting personnel and material from RF-based threats using ultra-wideband (UWB) transmission
First Claim
1. A method of protecting personnel and materiel from radio frequency (RF)-triggered explosive devices (RTEDs) comprising:
- associating predetermined interference parameters with a RTED transmission signal, wherein the RTED transmission signal comprises a bit stream;
creating one or more ultra-wideband (UWB) signals using the predetermined interference parameters; and
transmitting the one or more UWB signals to thereby interfere with the reception of the bit stream by a RTED receiver.

Abstract
An ultra wideband (UWB) jamming system comprises a processor, a memory, a pulse generator, one or more UWB transmitters, and one or more UWB antennas. In an exemplary embodiment of the present invention, the RF signals of a threat transmission or an RF-triggered explosive device (RTED) are evaluated and a set of interference parameters defined for the RF signal of that device. The interference parameters are predetermined to interfere with the reception or transmission of the RF signal. The interference parameters are sent to a pulse generator that drives one or more UWB transmitters to generate a signal has a statistically high probability of jamming or introducing an error in the threatening transmission.
