The Design and Implement of Acoustic Array Sensor Network Platform for Online Multi-target Tracking
2012 IEEE 8th International Conference on Distributed Computing in Sensor Systems, 2012Co-Authors: Yuanshi Li, Zhi Wang, Shuguo Zhuo, Jie Shen, Dahang FengAbstract:We present the design, implement and evaluation of a sensing platform for on-line multi-target tracking based on Acoustic Array networks, named Integrated Acoustic Array Sensor Network Tracker (IAASNT). To provide on-line multi-target tracking service, a well-designed system structure is proposed, composed by supporting components and associations between each part. Among these, IAASNT's multi-level low-power management and integrated tracking frame set it different from other related platforms. The integrated tracking frame is the core of the system and has been carefully designed, to achieve a self-acting tracking service. Finally, a series of experiments on system have been done to evaluate the performance of IAASNT. The tracking experiments on system show a perfect tracking performance in both noise-free and noisy environment, and the tracking precision can be within 5.8m in 300*300m area.

Acoustic Array Calibration and Signal Processing for UHE Neutrinos Generation
2011 IEEE Eighth International Conference on Mobile Ad-Hoc and Sensor Systems, 2011Co-Authors: W. Ooppakaew, S. Danaher, M. SaldanaAbstract:The calibration and design of an eighthydrophone linear Array has been developed for the generation of emulated Ultra High Energy (UHE) neutrino-induced pulses. The Acoustic Array simulates the Acoustic pulse created from a neutrino interaction in water by generating a coherently emitted Acoustic bipolar pulse. The calibrator is developed using signal processing methods using experimental measurements to characterise the hydrophone system. An 8 channel PIC hydrophone Array module has been built for processing and control. A linear Array simulation for the neutrino pulses production has been studied in order to predict the directivity and shape of the Acoustic bipolar pulse at the ANTARES neutrino detector.

A directional Acoustic Array using silicon micromachined piezoresistive microphones.
Journal of the Acoustical Society of America, 2003Co-Authors: David P. Arnold, Toshikazu Nishida, Louis N. Cattafesta, Mark SheplakAbstract:The need for noise source localization and characterization has driven the development of advanced sound field measurement techniques using microphone Arrays. Unfortunately, the cost and complexity of these systems currently limit their widespread use. Directional Acoustic Arrays are commonly used in wind tunnel studies of aeroAcoustic sources and may consist of hundreds of condenser microphones. A microelectromechanical system (MEMS)-based directional Acoustic Array system is presented to demonstrate key technologies to reduce the cost, increase the mobility, and improve the data processing efficiency versus conventional systems. The system uses 16 hybrid-packaged MEMS silicon piezoresistive microphones that are mounted to a printed circuit board. In addition, a high-speed signal processing system was employed to generate the Array response in near real time. Dynamic calibrations of the microphone sensor modules indicate an average sensitivity of 831 μV/Pa with matched magnitude (±0.6 dB) and phase (±1°)...

Cattafesta, Mark SheplakAbstract:The need for noise source localization and characterization has driven the development of advanced sound field measurement techniques using microphone Arrays. Unfortunately, the cost and complexity of these systems currently limit their widespread use. Directional Acoustic Arrays are commonly used in wind tunnel studies of aeroAcoustic sources and may consist of hundreds of condenser microphones. A microelectromechanical system ?MEMS?-based directional Acoustic Array system is presented to demonstrate key technologies to reduce the cost, increase the mobility, and improve the data processing efficiency versus conventional systems. The system uses 16 hybrid-packaged MEMS silicon piezoresistive microphones that are mounted to a printed circuit board. In addition, a high-speed signal processing system was employed to generate the Array response in near real time. Dynamic calibrations of the microphone sensor modules indicate an average sensitivity of 831 ? V/Pa with matched magnitude ??0.6 dB? and phase ??1°? responses between devices. The Array system was characterized in an anechoic chamber using a monopole source as a function of frequency, sound pressure level, and source location. The performance of the MEMS-based Array is comparable to conventional Array systems and also benefits from significant cost savings.
