Abstract
Summary
Field experiment using a buried DAS telecommunication cable shows that propeller aircraft are detectable on spectrograms of DAS data by their characteristic Doppler signature. Their parameters and trajectory can be estimated (using multiple DAS channels). The detection range is about 2 to 3 km. Detecting noise form jet aircraft requires a smaller gauge length.
