A terrestrial acoustic sensor array for detecting and preventing airspace collision with an unmanned aerial vehicle (UAV) includes a plurality of ground-based acoustic sensor installations, each of the acoustic sensor installations including a sub-array of microphones. The terrestrial acoustic sensor array may further include a processor for detecting an aircraft based on sensor data collected from the microphones of at least one of the plurality of acoustic sensor installations and a network link for transmitting a signal based on the detection of the aircraft to a control system of the UAV.

Laser light source geolocation. The system includes two spaced-apart ground based sensors for receiving light from a laser source that has been off-axis scattered by air molecules and particulates to form scattered light imagery. A processor operates on the imagery from the two sensors to geolocate the laser light source on the ground.

Technology relates to positional and quantitative analysis of noise emissions in a target area. Some embodiments have been developed to allow for triangulation of noise sources, thereby to assist in understanding noise levels originating from within the target area. While some embodiments will be described herein with particular reference to those applications, it will be appreciated that the present disclosure is not limited to such a field of use, and is applicable in broader contexts.
