Ultrasonics, 2014
In this article different techniques for localizing acoustic sources are described and the advantages/disadvantages of these techniques are discussed. Some source localization techniques are restricted to isotropic structures while other methods can be applied to anisotropic structures as well. Some techniques require precise knowledge of the direction

Chemical Plume Source Localization
IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2006This paper addresses the problem of estimating a likelihood map for the location of the source of a chemical plume using an autonomous vehicle as a sensor probe in a fluid flow. The fluid flow is assumed to have a high Reynolds number. Therefore, the dispersion of the chemical is dominated by turbulence, resulting in an intermittent chemical signal ...

Auditory localization of nearby sources. II. Localization of a broadband source
The Journal of the Acoustical Society of America, 1999Although many researchers have examined auditory localization for relatively distant sound sources, little is known about the spatial perception of nearby sources. In the region within 1 m of a listener’s head, defined as the “proximal region,” the interaural level difference increases dramatically as the source approaches the head, while the ...

Source Localization with Intelligent Surfaces
ICC 2022 - IEEE International Conference on Communications, 2022Source localization is essential for a wide range of applications. The efficiency of source localization in complex wireless environments can be improved via the use of reconfigurable intelligent surfaces (RISs). In this paper, we investigate the information inequality of RIS-aided localization systems.

EEG dipole source localization
IEEE Engineering in Medicine and Biology Magazine, 1998Considers using inverse solutions for determining source locations. Dipole source localization using EEGs recorded from the scalp is widely used to make estimates of the locations of sources of electrical activity in the brain. Such information can be very useful for both clinical and research applications.

Multi-Source Localization Strategies
2001Localization of multiple acoustic sources is an important task in many practical applications. However, in most cases adopted models are not fully adequate to describe real scenarios. In particular, in the presence of reverberation, the signal model should explicitly take into account both signals radiated by multiple sources and reflections.

Cerebral Source Localization Paradigms - Spatiotemporal Source Modeling
Brain and Cognition, 1995Spatiotemporal source modeling (STSM) attempts to interpret multichannel scalp recordings in terms of their contributing brain areas. Localization accuracy is generally limited by spatially correlated residual noise and by modeling simplifications. For signals emanating simultaneously from several sources, however, correct interpretation of the source ...

From EEG source localization to source imaging
Acta Neurologica Scandinavica, 1994A new functional imaging technique, "FOCUS", has been developed to transform the traditional scalp EEG into an image of source activities. The image is based on multiple spatio-temporal dipole models and consists of gross spatial patterns and source waveforms reflecting the estimated activities of the different brain regions.

This paper description Sound Source Localization problem. At present, Sound Source Localization is a developing sector in the measurement of acoustic signals. The aim of this sector is to locate the source of the acoustic signal and to evaluate the angle and distance between the sources of the measuring system.

Overview of dipole source localization
Physical Medicine and Rehabilitation Clinics of North America, 2004Truly accurate dipole source localization relies on having (1) reliable, artifact-free EP/ERP (or magnetoelectroencephalogram) data to start with; (2) landmark and electrode position data obtained with a three-dimensional digitizer; (3) MRI (or CT) data from the same subject (with a means to measure the same landmarks); (4) the capability to apply ...
