Source Localization with Acoustic Vector Sensors
In this paper a localization method is analyzed, which uses Acoustic Vector Sensors (AVS). An AVS measures the directed velocity and the pressure in an area approaching a single point. In order to localize sound sources, the Multiple Signal Classification (MUSIC) was applied, which determines the signal and the noise components. MUSIC only uses the noise components (Noise Subspace) to estimate ...
متن کاملEnergy Based Acoustic Source Localization
A novel source localization approach using acoustic energy measurements from the individual sensors in the sensor field is presented. This new approach is based on the acoustic energy decay model that acoustic energy decays inverse of distance square under the conditions that the sound propagates in the free and homogenous space and the targets are pre-detected to be in a certain region of the ...
متن کاملAcoustic Source Localization in a Heterogeneous Network
I present a potential design of a heterogeneous acoustic sensing network comprised of the Acoustic Embedded Networked Sensing Box (ENSBox) and the Berkeley Mica2 platforms. I also present one potential method of leveraging the presence of Mica2 motes to improve acoustic source localization. More specifically, I present a method of rejecting grating lobes, which may be present in direction-ofarr...
متن کاملSource Localization in Random Acoustic Waveguides
Mode coupling due to scattering by weak random inhomogeneities in waveguides leads to loss of coherence of wave fields at long distances of propagation. This in turn leads to serious deterioration of coherent source localization methods, such as matched field. We study with analysis and numerical simulations how such deterioration occurs and introduce a novel incoherent approach for long range ...
متن کاملTDOA denoising for acoustic source localization
In this manuscript, we formulate the problem of denoising Time Differences of Arrival (TDOAs) in the TDOA space, i.e. the Euclidean space spanned by TDOA measurements. The method consists of pre-processing the TDOAs with the purpose of reducing the measurement noise. The complete set of TDOAs (i.e., TDOAs computed at all microphone pairs) is known to form a redundant set, which lies on a linear...
