Scatter
Scatter is a software package designed to rapidly calculate the amplitudes and intensities of ultrasonic waves scattering from rough surfaces, using analytical and theoretical modelling methods.
It has capability to calculate the reflection amplitudes for finite planar rough defects in two-dimensional space. Outputs are normalised with respect to the amplitudes that would be expected for smooth defects of the same size. The predicted amplitudes are evaluated using the Kirchhoff Approximation (KA) scattering integrals, which are implemented for a variety of different kinds of excitations, source and receiver set-ups and material parameters. The calculations incorporate both compression and shear elastic wave modes, with mode conversions.
It was developed, and is supported, by members of the Non-Destructive Evaluation (NDE) research group at Imperial College London. It runs on Microsoft Windows, MacOs, and Linux platforms. It is made available to users only via the developers and is released on a restricted basis.
The capabilities of Scatter can be seen in the user manual.
