Matched mode method of passive source localization

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

Passive Source Localization: Algorithms and Analysis

Finding the position of a passive source based on measurements from an array of spatially separated sensors has been an important problem in radar, sonar, global positioning system, mobile communications, multimedia and wireless sensor networks. Time-of-arrival (TOA), time-differenceof-arrival (TDOA), received signal strength (RSS) and direction-of-arrival (DOA) of the emitted signal are common...

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...
