Unmanned Aerial Vehicles

Unmanned aerial vehicles (fixed wing or multi copters) may pose a threat to society.

From an acoustic point of view, there is a difference between a:

  • fixed wing, that is acoustically speaking a tonal, narrow banded sound source
  • multi copter, that is acoustically speaking a wide banded sound source

From a signal processing point of view, a tonal sound source is easier to detect, localise and track.

Obviously, the detection range depends upon:

  • the design parameters of the unmanned aerial vehicle ( e.g weight, number –and diameter of propeller blades, rpm )
  • weather conditions

As a rule of thumb, toy shop bought unmanned aerial vehicles can be detected, localised and tracked in a range between 250-1000 meters.
