Method of detecting and tracking an unmanned aerial vehicle, the method comprising, at a detector unit 300 comprising a first microphone 301a and a second microphone 303a: monitoring for a sound associated with the presence of the unmanned aerial vehicle in the vicinity of the detector unit; in response to the monitoring indicating the presence of the unmanned aerial vehicle, determining, at the detector unit, a phase delay between the sound as received at the first microphone and the sound as received at the second microphone; on the basis of the determined phase delay and a known separation of the first microphone and the second microphone, determining, at the detector unit, an azimuth angle to the unmanned aerial vehicle from the detector unit; and transmitting, to a computing node, the determined azimuth angle for use in determining a location of the unmanned aerial vehicle. The detector unit preferably includes three microphone pairs, 301a, b, c, 303a, b, c.
