A directional spectrum evolution model for ship noise

2023

Open Access Peer Reviewed Research Article

Journal of the Acoustical Society of America

Brown, M.G.,

A radiation transport equation that describes the spatiotemporal evolution of the directional spectrum of underwater acoustic noise is presented and applied to ship noise. The model...
