An interactive graphical user interface (GUI) for displaying frequency, amplitude and direction information provided by an intelligence system is provided comprising: a plot of RF versus amplitude, and a graph of frequency versus direction. The intelligence system has 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 direction. The GUI is updated continuously in near real time. Methods of operating the GUI are also provided.
