As part of a research initiative within the US Army Research Laboratory, we investigate acoustic sensing capability from UAVs for remote Intelligence Surveillance and Reconnaissance (ISR) applications. Acoustic sensing from UAVs offers several advantages over acoustic sensing on the ground including: (i) longer detection ranges due to upward refraction and (ii) a single elevated acoustic array (versus multiple acoustic arrays on the ground) can provide a pointing vector to the acoustic source on the ground. However, there are technical challenges with having acoustic sensors on UAVs which involve self generated noise from the platform and the air flow. In this paper, we describe our current work with acoustic sensors on small UAV platforms and present preliminary processing results from a recent field experiment.
