An acoustic-signature based method of estimating the flight trajectory of low-altitude flying aircraft that only requires a stationary microphone array is proposed. This method leverages the Doppler shifts of engine sound to estimate the closest point of approach distance, time, and speed. It also leverages the acoustic phase shift over the microphone array(More)
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(More)
