Paper Abstract

As commercial operating systems such as Microsoft Windows move from the desktop to the embedded world and low-power, low-cost embedded CPU performance increases the distinction between dedicated embedded systems and laboratory demonstration systems is blurring. Signalscape, Inc. has developed a highly flexible acoustic signal processing system with real-time performance on Pentium II class desktop computers running Microsoft Windows. In a recently awarded DARPA program, Rockwell Science Center, Signalscape, and their partners are moving the flexibility and capabilities of Signalscape's many tool kits onto low-cost, low-power systems for unattended sensor applications. In this paper we discuss the results of the first demonstrations of acoustic beamforming using a small network of sensors.
