Full reconstruction of acoustic wavefields by means of pointwise measurements
A novel method for full wavefield reconstruction from pointwise measurements data collected by a vertical receiver array is proposed for geoacoustic waveguides of a shallow sea. This method is based on a generalization of the Whittaker–Shannon interpolation formula to the case of a waveguide cross-s...

| 520 | |a A novel method for full wavefield reconstruction from pointwise measurements data collected by a vertical receiver array is proposed for geoacoustic waveguides of a shallow sea. This method is based on a generalization of the Whittaker–Shannon interpolation formula to the case of a waveguide cross-section. The generalization is obtained by means of the so-called discrete variable representation. The method can be implemented both for tonal and pulse signals. It is shown that the method is robust against array distortions and ambient noise of moderate amplitude. Efficiency of reconstruction is verified by means of numerical simulation with a model of a shallow-sea waveguide. It is shown that the presence of sound attenuation in the seabottom results in the possibility to accurately reconstruct the field using a relatively sparse receiver array. | ||

Full reconstruction of acoustic wavefields by means of pointwise measurements |
| abstract |
A novel method for full wavefield reconstruction from pointwise measurements data collected by a vertical receiver array is proposed for geoacoustic waveguides of a shallow sea. This method is based on a generalization of the Whittaker–Shannon interpolation formula to the case of a waveguide cross-section. The generalization is obtained by means of the so-called discrete variable representation. The method can be implemented both for tonal and pulse signals. It is shown that the method is robust against array distortions and ambient noise of moderate amplitude. Efficiency of reconstruction is verified by means of numerical simulation with a model of a shallow-sea waveguide. It is shown that the presence of sound attenuation in the seabottom results in the possibility to accurately reconstruct the field using a relatively sparse receiver array. |
