Patent ID: 7558582

Claim:
A directional electronic signal geolocation and identification system, comprising: a wideband signal collection front end subsystem, 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 each said antennae means to said RF transmitter; and apparent location determination means for determining an apparent location of said RF signal transmitter from said determined directions; 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 geographical location correction means for determining a corrected geolocation of said RF transmitter, said geographical location correction means comprising correction means for comparing said apparent location to a calibrated apparent location to determine a corrected geolocation of said RF transmitter.
