Abstract: The test results found that the EMI impact depended on the UWB power that fell within the receiver passband. Specifically, EMI occurred when the average power in the receiver passband was approximately equal to the desired signal level of the receiver. One waveform, TW7, did not cause EMI because the average power was too low. Three waveforms, TW1, TW2, and TW6 only caused EMI when the receiver was tuned to the frequency of the UWB spectral component. Three waveforms, TW3, TW4, and TW5, caused EMI at all receiver frequencies. As noted, these tests were performed to determine the susceptibility of various RF receiver (radars and communications systems) devices to UWB signals. The tests were not intended to evaluate the use of UWB signals for jamming purposes.

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.
