2. Acoustic Detection Arrays
Using sophisticated microphone arrays and sound processing techniques, acoustic detection technology finds drones by their distinct sound signatures. By examining the unique noise patterns created by their propellers and motors, these systems can identify drones up to several hundred meters distant. Modern acoustic detection systems use artificial intelligence to separate drone noises from background noise—such as birds, aircraft, or city activities. Urban settings where conventional radar systems can suffer with interference from buildings and structures let the technology shine. By extending their drone sound signature databases and strengthening their capacity to run efficiently in different acoustic situations and weather conditions, manufacturers keep improving these systems.
