Classification, positioning, and tracking of drones by HMM using acoustic circular microphone array beamforming is a research paper that addresses issues with identifying and tracking drones.
The paper proposes an acoustic-based method of positioning and tracking drones that include three main focal points:
-Scan the sky with switched beamforming to find sound sources;
– perform classification with a hidden Markov model (HMM); and
– if the sound source is a drone, use the recorded sound as a reference signal for tracking based on adaptive beamforming.
