Raypath Separation With a High-Resolution Algorithm in a Shallow-Water Waveguide
IEEE Journal of Oceanic Engineering
One intriguing property that is exploited by ocean acoustic tomography (OAT) is that acoustic signals travel in a multipath. As the first step of OAT, each ray path should be identified with a particular travel time. However, the set of multipath rays generated by an emitted signal is correlated or coherent, as they are produced by reflection and or by refraction in propagation. In this paper, a highresolution method called smoothing-Multiple Signal Classification Active Large Band (MUSICAL) isdoi:10.1109/joe.2017.2660778 fatcat:ow5ifn5upnd3noat6iwcesfmcm
