Development Towards the use of Beamforming and Adaptive Line Enhancers for Audio Detection of Quadcopters
… usage of Unmanned Aerial Systems (UASs), such as quadcopters and hexacopters, has steadily increased over the past few years in both recreational and commercial use. This increased availability to purchase such systems has also given rise to many safety and security concerns. A common concern is …
