Estimation of low-altitude moving target trajectory using single acoustic array

The Journal of the Acoustical Society of America, 2016
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.
