Improved multipath time delay estimation using cepstrum subtraction

Autor: Ferguson, Eric L., Williams, Stefan B., Jin, Craig T.

When a motor-powered vessel travels past a fixed hydrophone in a multipath environment, a Lloyd's mirror constructive/destructive interference pattern is observed in the output spectrogram. The power cepstrum detects the periodic structure of the Llo

Sound Source Localization in a Multipath Environment Using Convolutional Neural Networks

Autor: Ferguson, Eric L., Williams, Stefan B., Jin, Craig T.

The propagation of sound in a shallow water environment is characterized by boundary reflections from the sea surface and sea floor. These reflections result in multiple (indirect) sound propagation paths, which can degrade the performance of passive

Convolutional Neural Networks for Passive Monitoring of a Shallow Water Environment using a Single Sensor

Autor: Ferguson, Eric L., Ramakrishnan, Rishi, Williams, Stefan B., Jin, Craig T.

A cost effective approach to remote monitoring of protected areas such as marine reserves and restricted naval waters is to use passive sonar to detect, classify, localize, and track marine vessel activity (including small boats and autonomous underw
