dc.description.abstract | Ray-based Blind Deconvolution (RBD) is a technique that can estimate the channel impulse response of a receiver array even in the absence of acoustic source information. Combined with array invariant method, RBD has been applied in several studies, such as ship localization. In this talk, the channel impulse response was estimated through RBD for the ship noise of R/V Onnuri received by a 16-channel vertical line array moored at the bottom during the Shallow-water Acoustic Variability Experiment (SAVEX-15). The bottom loss is estimated as a function of grazing angle using the ratio of intensity impulse responses between direct path and bottom bounce path after compensating for the transmission loss for two paths. Finally, geoacoustic parameters for sediment at the SAVEX-15 site are estimated by comparing the estimated bottom loss to the Rayleigh bottom-loss model. Inversion results will be discussed in comparison with those presented in the literature. [Work supported by the Ministry of Oceans and Fisheries of Korea (PM63010, 2022).] | - |
