Patent ID: 7099369

Claim:
A directional electronic signal jamming system, comprising: a wideband signal collection front end, comprising: a wideband receiver for receiving RF signals transmitted by an RF signal transmitter across a broad spectrum said receiver comprising first, second and third antennae means for receiving RF signals simultaneously, said antennae means in geographically spaced relation; a digitizer for creating an individual continuous stream of digitized data representing each said antennae means' received RF signals; a digital data conversion means for converting said individual digitized data stream into FFT frequency bins by individual stream; direction determination means for determining a direction from said antennae means to said RF transmitter; directional lockout means responsive to said direction determination means for selectively enabling jamming signal transmissions against said RF transmitter only if said direction to said RF transmitter from said antennae means is within a bearing sector of interest; a signal evaluation logic module, comprising: a comparing means for comparing each said frequency bin to configurable preset lockout frequency bins; a peak detection means for evaluating and calculating the amplitude value for each bin by using a configurable number of data point samples for each of those bins; a windowing means for evaluating and calculating the amplitude value for each bin by using a configurable number of data point samples for each of those bins; and a priority selection means for evaluating the prioritization of jammer signal targets based upon configurable settings; an internal transmitter also responsive to said comparing, peak detection, windowing, and priority logic for transmitting a jamming signal on said frequency of interest; and an internal cycle generator timing circuit for the proper high-speed automatic triggering of all modules of the directional electronic signal jamming system.
