Abstract: A frequency visualization apparatus for detecting and displaying one or more specific sets of energy waves based on one or more of defined discrete sets of frequency ranges is disclosed, the apparatus including two or more directional radio frequency antennas for capturing a field of view, such orientation comprising a detector array, each antenna configured to output a specific voltage based on the strength of the intercepted radio waves, two or more voltage amplifiers in communication with the one or more radio frequency antennas, two or more analog to digital converters, a digital memory apparatus connected to the two or more converters for receiving and storing the digital data in a numeric array, a processor connected to the digital memory apparatus, and a display connected to the processor for displaying a visual array comprising visual array elements, each visual array element corresponding to a specific antenna of the detector.

Abstract: A system and apparatus for: (i) receiving an image of a visually perceptible scene; (ii) sensing the presence and intensity of signals in a selected frequency band, which may include one or more of radio frequency, microwave, infrared, visible and ultraviolet, in part or all of the scene; (iii) displaying the frequency band as a visually distinguishable overlay on the visually perceptible scene; and (iv) indicating whether the signal intensity for a selected frequency interval is changing with passage of time.
