Passive Acoustic Source Tracking Using Underwater Distributed Sensors

Distributed Passive Sonar System for Performance Evaluation of Low Depth Underwater Acoustic Source Localization Using Relative Time Delay Based Techniques

This paper presents the preliminary studies of a distributed passive sonar system for the localization and tracking of underwater acoustic sources. The techniques under test are one referred to as hyperbolic and mainly developed by Carter and another proposed by the authors and based on neural network processing. Both techniques are supported on the measurement of the relative time delay of an ...

Passive acoustic and electromagnetic underwater tracking and classification using data fusion

not more than 200 words) An interesting possibility for improved surveillance capabilities in challenging underwater environments and against targets with low acoustic signatures is the use of multisensor systems combined with dataor information fusion. This work describes how data fusion can be used for tracking and classifying targets using passive underwater acoustic and electric field senso...

Improving Passive Time Reversal Underwater Acoustic Communications Using Subarray Processing

Multichannel receivers are usually employed in high-rate underwater acoustic communication to achieve spatial diversity. In the context of multichannel underwater acoustic communications, passive time reversal (TR) combined with a single-channel adaptive decision feedback equalizer (TR-DFE) is a low-complexity solution to achieve both spatial and temporal focusing. In this paper, we present a n...
