Randomized group testing for acoustic source localization
SPIE Proceedings, 2010Undersea localization requires a computationally expensive partial differential equation simulation to test each candidate hypothesis location via matched filter. We propose a method of batch testing that effectively yields a test sequence output of random combinations of location-specific matched filter correlations, such that the computational run

Localization of underwater wide band acoustic sources
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991In this work, the signal processing methods are used for determining the direction of arrival of the wideband acoustic signals. The performance of several frequency methods using the incoherent or coherent signal subspace are tested on the experimental data. The temporal method is used with the same data. >

Ships as sources of opportunity in acoustic source localization
The Journal of the Acoustical Society of America, 2015Ships, which can be tracked using the Automatic Identification System (AIS), represent underutilized acoustic sources of opportunity (SOP) that can potentially be used to localize unknown sources, invert for environmental parameters, and extract information about the ocean environment such as the local time dependent Green’s Function. An application of

Acoustic Source Localization and Deconvolution-Based Separation
Journal of Computational Acoustics, 2015This paper examines two fundamental issues in sound field analysis: acoustic sources localization and separation. Algorithms are developed to locate and separate acoustic signals on the basis of plane-wave decomposition. In the localization stage, directions of plane waves are determined using either minimum variance distortionless response (MVDR ...

Acoustic Source Localization with Distributed Smartphone Arrays
2015 IEEE Global Communications Conference (GLOBECOM), 2014Acoustic source localization in sensor network is a challenging task because of severe constraints on cost, energy, and effective range of sensor devices. To overcome limitations in existing solutions, this paper formally describes, designs, implements, and evaluates a Hamming Distance-based Method for Acoustic Source Localization, i.e., HammingLoc, in

Detection, Enumeration and Localization of Underwater Acoustic Sources
2019 27th European Signal Processing Conference (EUSIPCO), 2019The problem of passive detection, enumeration and localization of underwater objects is of great interest in several applications of sonar. Source localization requires prior knowledge of the number of sources. Therefore, detection is followed by estimation of the number of sources, and finally localization.

Particle swarm localization of acoustic sources in the presence of reverberation
2006 IEEE International Symposium on Circuits and Systems, 2006In this work a novel approach to acoustic source localization in reverberant environments is introduced. The proposed method effectively employs particle filtering (PF) and particle swarm optimization (PSO) in an integrated framework. Source localization is viewed as a global minimization problem where the solution is searched by properly exploiting ...

Acoustic Source Localization With Distributed Asynchronous Microphone Networks
IEEE Transactions on Audio, Speech, and Language Processing, 2013We propose a method for localizing an acoustic source with distributed microphone networks. Time Differences of Arrival (TDOAs) of signals pertaining the same sensor are estimated through Generalized Cross-Correlation. After a TDOA filtering stage that discards measurements that are potentially unreliable, source localization is performed by minimizing
