Matched-field source localization with non-synchronized sensor arrays

Broadband matched-field source localization

A straightforward algorithm for broadband matched-field source localizaton is developed and subsequently applied to experimental data. For the two-receiver case, the algorithm involves correlating modeled and measured cross spectra nd summing coherently over frequency. The extension to the multiple-receiver case is to perform the two-receiver algorithm on each pair of hydrophones and sum the co...

Electromagnetic matched field processing for source localization

Matched eld processing (MFP) refers to signal and array processing techniques in which, rather than a planewave arrival model, complex-valued (amplitude and phase) eld predictions for propagating signals are used. Matched eld processing has been successfully applied in ocean acoustics. In this paper the extension of MFP to the electromagnetic domain, i.e., electromagnetic (EM) MFP (EM-MFP) is d...

Passive Source Localization of Sensor Arrays

Signal Subspace Techniques for Source Localization with Circular Sensor Arrays

Estimating the directions-of-arrival (DOAs) of propagating plane waves is a problem of interest in a variety of applications including radar, mobile communications, sonar, and seismology. The widely studied uniform linear array (ULA) can only provide estimates of source bearings relative to the array axis. A planar. array is required if estimates of source azimuth and elevation are required (2D...

The impact of wind-generated bubble layer on matched field sound source localization in shallow water (Research Article)

This paper investigates the effect of the wind-generated bubble layer on the underwater sound source localization in the Persian Gulf shallow-water environment through computer simulation and the matched field processing technique. An underwater sound source of 2-10 kHz located at depths of 10, 45, and 75 m was considered at a distance of 4 km from a linear vertical receiver array. The estimati...
