Sample interview questions: Can you explain the concept of acoustic scattering tensors and their measurement?
Sample answer:
Acoustic Scattering Tensors
Acoustic scattering tensors describe the scattered wave field generated by an incident wave interacting with an object. They provide information about the object’s size, shape, orientation, and material properties.
The scattering tensor is a fourth-rank tensor, with 36 components that relate the incoming and scattered wave vectors and polarizations. Each component represents the scattering strength in a particular direction and polarization.
Measurement of Acoustic Scattering Tensors
Acoustic scattering tensors can be measured using various techniques:
- Bistatic scattering: Measurement of the scattered wave field at a single receiver location. Analysis of the received signal yields information about the scattering tensor components.
- Multistatic scattering: Measurement of the scattered wave field at multiple receiver locations. By combining data from different receivers, the full scattering tensor can be reconstructed.
- Inverse scattering methods: Numerical methods tha… Read full answer
