Sound Source Localization in a Multipath Environment Using Convolutional Neural Networks
Eric L. Ferguson, Stefan B. Williams, Craig T. Jin
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)…
