Patent ID: 7724680

Claim:
An interactive graphical user interface (GUI) for displaying frequency, amplitude and direction information provided by an intelligence system having a front end to generate digital data based on received radio frequency (RF) signals, a post processing stage to process the digital data, and a direction finding stage to prevent the post-processing stage from processing portions of the digital data that correspond to RF signals arriving from a direction other than a predetermined range of directions, comprising: a plot of RF versus amplitude based on the frequency information and the amplitude information provided by the intelligence system, displayed simultaneously with a graph of frequency versus direction based on the frequency information and the direction information provided by the intelligence system; wherein the frequency information of both the plot and the graph covers a range of simultaneously monitored frequencies of the RF signals arriving from the predetermined range of directions; and wherein user interaction with the graph sets i) the predetermined range of directions, and ii) a range of frequencies, which predetermined range of directions and range of frequencies configure the direction finding stage.
