Geopsy software provide powerful tools for advanced signal processings, for instance ambient vibration array processings or H/V spectral ratio. These tools are available under the menu Tools. The following advanced signal processing tools are available:
- F-K : conventional frequency wavenumber technique
- High resolution F-K : high resolution frequency wavenumber technique
- MSPAC : modified spatial autocorrelation technique
- Linear F-K for active experiments : multichannel analysis of surface waves
- Linear F-K for passive experiments : multichannel analysis of surface waves for ambient vibrations
- Damping : computation of damping factor for soil or structure
- Spectrum : Fourier amplitude spectra
- Spectrum Rotate : Fourier amplitude spectra in the horizontal space
- H/V spectral ratio : Horizontal-to-Vertical spectral ratio
- H/V Rotate : rotate Horizontal-to-Vertical spectral ratio
- Noise reduction
- Particle motion
- Refraction with NA: obsolete
- Time frequency analysis
- Structure spectrum
The advanced signal processing tools are also available by clicking on the icons in the toolbar. It is possible to customize the toolbar in the menu preferences menu.
