Dictionary learning of sound speed profiles
WebThe inverse problem is formulated as a state-space model with a state equation for the time-evolving sound speed profile and a measurement equation that incorporates acoustic measurements via a hydrophone array. Empirical orthogonal functions are introduced to reduce the unknown parameters in inversion algorithm. WebThe water depth is 160 m. Sound speed, density, and attenuation are 1800 m/s, 2.0 g/cm 3 , and 0.1 dB/λ, respectively. ... from publication: Compressive Sound Speed Profile Inversion Using ...
