Abstract:
1. An operator station for communicating with a mobile electronic observation device capable of detecting radio frequency signals in a given geographical area, the operator station comprising: a communication device comprising a transmitter and receiver, said transmitter is adapted to transmit a plurality of control and data signals to said mobile electronic observation device, wherein said plurality of control signals include a control signal to said mobile electronic observation device to transmit a signal which triggers transmission of a device identifier by one or more devices adapted to transmit or receive electromagnetic frequency signals; an input and output section adapted to permit a user to receive information from, input data into, and otherwise operate said station and electronic observation device; a location determination section adapted to determine a location of the operator station; wherein said receiver is configured to receive a source signal from the mobile electronic observation device, the source signal including a first event pattern data comprising a location of said mobile electronic observation device and time associated with a detected radio frequency signal that the mobile electronic observation device has determined matches one or more of a predetermined plurality of characteristics, said plurality of characteristic comprising said device identifier; a controller operably coupled to the receiver and including a clock, the controller configured to process the source signal detected by said receiver at said operator station and to create a second detection event pattern data comprising a location of an antenna coupled to said receiver and time of the detected radio frequency signal at the receiver, to compare the first detection event pattern data of the detected radio frequency signal within the source signal and the second detection event pattern data of the detected radio frequency signal by the controller, and to determine a source location of the source signal comprising the detected radio frequency signal and assign a first class of data point representative thereof; and a user output operably coupled to the controller and configured to provide a graphical representation of said devices adapted to transmit or receive electromagnetic frequency signals associated with the source location represented by the data point.
