Direction Of Arrival estimates with vector sensors: first results of an atmospheric infrasound array in the Netherlands

Abstract

The Royal Netherlands Meteorological Institute has continuously operated an outdoor atmospheric infrasound array containing 37 pairs of particle velocity sensors (Microflown) and 6 pressure sensors in the north of the Netherlands in the fall of 2008. As initial results, we detected transients caused by distant aircrafts and calculated their Direction of Arrival (DOA). A nearby sound-source, probably an agricultural vehicle passing on the nearby road or field, could be tracked. Furthermore, we compare DOA estimates using the amplitudes of the vector components of the particle velocity measured at single stations with those of classical beamforming and discuss the prospects for underwater applications.
