Abstract

The invention is directed to a UAV, system, and method for radio frequency spectral analysis. Accordingly, an unmanned aerial vehicle (UAV) having a flight body, a flight module, a geolocation module, and a signal detection module is utilized to detect and store signal data associated with various radio signal(s) during flight. The signal data may then be displayed on a processing device to provide a user with a visualization of the signal data parameters in various points of three dimensional space and at particular recorded times.
