Acoustic detection and tracking of UAS targets
Christian G. Reiff · The Journal of the Acoustical Society of America · 2016
Acoustic detection using a Minimum Variance Distortionless Response (MVDR) method and tracking of Unmanned Aircraft System (UAS) targets with the MVDR results over time will be presented. The acoustic environment was complex with surf noise, wind, road traffic, air traffic, and aircraft hangar noise. The targets were gas and electric fixed wing UAS as well as electric multi-rotor quadcopters. Scenarios with the UAS target leaving, incoming, and with multiple simultaneous targets are addressed. Tracking results are evaluated through comparison with GPS based UAS ground truth tracks.
