15 صفحه اولInversion of Scholte wave dispersion and waveform modeling for shallow structure of the Ninetyeast Ridge
The construction of S-wave velocity models of marine sediments down to hundreds of meters below the seafloor is important in a number of disciplines. One of the most significant trends in marine geophysics is to use interface waves to estimate shallow shear velocities which play an important role in determining the shallow crustal structure. In marine settings, the waves trapped near the fluid–...
متن کاملA Radiative Transfer Model for Acoustic Propagation in Ocean Sediment Layers
The propagation of mid-frequency (1-10 kHz) acoustic waves in shallow water regions (depths of 100200 m) is strongly influenced by the characteristics of the ocean bottom. While there has been much progress in developing and validating bottom scattering models, much of the focus has been in the high frequency regime with comparatively less focus in the mid-frequency. This is an important topic,...

15 صفحه اولSensitivity Analysis of Brown Model Waveform in Radar Altimetry
In satellite altimetry (radar altimetry), the altimeter emits a pulse, with known power, to the earth surface and receives it back continuously to determine of the sea surface height. The time series of the mean returned power is recorded individually at satellite as the so-called waveform. Analytical model for the waveform is first introduced by Brown, which consists of six parameters: signif...
