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...
متن کاملCross correlation matched field localization for unknown emitted signal waveform using two-hydrophone
Source localization is a crucial issue in underwater acoustics. Traditional matched field processing (MFP) use large vertical arrays to locate an underwater acoustic target. However, the use of the large arrays not only increases equipment and computational cost but also some problems such as element failures and array title degrades the localization performance. In this paper, the matched fiel...
متن کاملModel-based Underwater Acoustic Source Localization and Speed Estimation Using Hf Transmissions
This work addresses the problem of inferring side information about an underwater acoustic (UWA) channel, particularly the spatial transmitter/receiver configuration and relative speed vector from the environmental signature imprinted on high-frequency (HF) communication signals by the propagation medium. We adopt a framework for representing UWA time varying channels using a 3-dimensional Dela...
متن کاملParallel implementation of underwater acoustic wave propagation using beamtracing method on graphical processing unit
The mathematical modeling of the acoustic wave propagation in seawater is the basis for realizing goals such as, underwater communication, seabed mapping, advanced fishing, oil and gas exploration, marine meteorology, positioning and explore the unknown targets within the water. However, due to the existence of various physical phenomena in the water environment and the various conditions gover...
