METHOD AND APPARATUS FOR PROTECTING PERSONNEL FROM RF-TRIGGERED EXPLOSIVE DEVICES (RTED) USING ULTRA-WIDEBAND (UWB) TRANSMISSION
First Claim
1. A method of protecting personnel from radio frequency (RF)-triggered explosive devices (RTEDs), wherein the RTED is intended to explode upon reception of a RTED transmission signal at a RTED receiver, comprising:
- associating predetermined interference parameters with the RTED transmission signal, wherein the RTED transmission signal comprises a bit stream;
creating an ultra-wideband (UWB) signal meeting the predetermined interference parameters; and
transmitting the UWB signal thereby interfering with the reception of the bit stream by the RTED receiver.

Abstract
An ultra wideband (UWB) jamming system comprises a processor, a memory, a pulse generator, a UWB transmitter, and an UWB antenna. In an exemplary embodiment of the present invention, the RF signals of the RTED triggering device 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 of the RF signal of that device by a RTED receiver. The interference parameters are sent to a pulse generator that drives a UWB transmitter to generate a signal has a statistically high probability of introducing an error in a bit stream of the RTED signal before it is received by the RTED receiver thereby preventing detonation of the RTED.
