Power Estimation of Acoustic Sources by Sensor Array Processing
A constant problem is to localize a number of acoustic sources, to separate their individual signals and to estimate their strengths in a propagation medium. An acoustic receiving array with signal processing algorithms is then used. The most widely used algorithm is the conventional beamforming algorithm but it has a very low resolution and high sidelobes that may cause a signal leakage proble...
متن کاملAcoustic vector-sensor array processing
Existing theory yields useful performance criteria and processing techniques for acoustic pressure-sensor arrays. Acoustic vector-sensor arrays, which measure particle velocity and pressure, offer significant potential but require fundamental changes to algorithms and performance assessment. This thesis develops new analysis and processing techniques for acoustic vectorsensor arrays. First, the...
متن کاملSensor Array Processing for Scattered Sources
In the search of improved capacity and performance in wireless communication systems, antenna arrays have emerged as a promising technique. In these applications, as well as radar and other sensor array applications, it is important to have a good model of the propagation channel. This thesis deals with one such model an environment where the signal of each source is scattered by a large number...
متن کاملDistributed Sensor Array Processing of Wideband Acoustic Signals
We present performance analysis for source localization when wideband aeroacoustic signals are measured at multiple distributed sensor arrays. The acoustic wavefronts are modeled with perfect spatial coherence over individual arrays and with frequency-selective coherence between distinct arrays, thus allowing for random fluctuations due to the propagation medium when the arrays are widely separ...
متن کاملCoherent Acoustic Array Processing and Localization on Wireless Sensor Networks
Advances in microelectronics, array processing, and wireless networking have motivated the analysis and design of low-cost integrated sensing, computing, and communicating nodes capable of performing various demanding collaborative space–time processing tasks. In this paper, we consider the problem of coherent acoustic sensor array processing and localization on distributed wireless sensor netw...
