Paper Abstract

Networks of unattended acoustic ground sensors can be used to detect and accurately track high-speed airborne acoustic sources. While it is possible, in principle, to estimate altitude using networks of two-dimensional microphone arrays, the high sensitivity of this configuration significantly limits performance. This work shows that the addition of elevated microphones and appropriate signal processing can significantly improve performance. Airborne source tracking results from a field experiment are compared for the use of a small orthogonal three-microphone ground plane array versus the same array with an elevated microphone added.
