Both detection and tracking are conducted by identifying and tracking the drone's video signal. Drone detection is performed by first creating a spectrum mask based on the current RF environment. Creating the mask is an automated process where spectrum activity is measured. The mask is then set at a user-defined offset, usually by 3 to 5 dB above the RF spectrum measurements power level. See Configure Tracking Bands for details outlining masks.

Any subsequent violations of the spectrum mask are considered suspicious. Further analysis of this signal then occurs to determine whether the mask violation is due to drone presence. When it is determined with a high probability that a drone is present, the tracker API software is automatically engaged to locate, follow, and track the drone positions. Signal tracking is then logged and mapped as shown in Figure: AeroShield API Software GUI.

The frequencies to be scanned for drone presence are selectable by the user. Typically, these frequency channels are set in the ISM bands (2.4 GHz and 5.8 GHz). However, the software allows users to define additional channels as needed. The bands listed below will be 'hard coded', (i.e. the user can select UHF, ISM 2.4 GHz, ISM 5.8 GHz by name and the start/stop frequencies will automatically be used). See Table: Drone Frequencies for the ISM band frequencies used.
