Target tracking using acoustic signatures of light-weight aircraft propeller noise
Jianfei Tong, Yu Hen Hu, Ming Bao, Wei Xie · 2013
Acoustic signatures of aircraft engine and propeller noise are investigated in the context of target tracking. Harmonics in spectrograms of light airplanes collected by a stationary microphone array on the ground are analyzed. Using a model of Doppler frequency shifts, the target speed and height may be estimated from the spectrogram of recorded acoustic signal. These initial results highlight the potential of using the acoustic signatures for precision moving target detection and tracking.
