Signals emitted from an unmanned aerial vehicle (UAV) 8 of a UAV-type are detected during controlled use in a clean environment 3 (e.g. using signal detectors 5). The signals are analysed to identify signal characteristics of the UAV-type, which are stored in a remote database 2. The UAV-type is validated when the stored signal characteristics are determined to be unique to the UAV-type, either in isolation or in combination. The database may be pre-populated with signal characteristics of commercially available UAV types. A UAV of one of the validated UAV-type is then detected by monitoring a protected airspace 7 for its stored unique signal characteristics. The signals may include radio frequency (RF) signals, e.g. UAV, controller or ADS-B signals. The signals may include visual signals (e.g. detected using a pan, tile and zoom camera) or a pattern of movement (e.g. detected using a radar or visual camera). The detected UAV’s position may be monitored.
