Geopsy software provides powerful tools for advanced signal processings, for instance ambient vibration array processings or H/V spectral ratio. A plug-in mechanism allows you to install only selected tools corresponding to your need. Through the menu Preferences it is possible to add (or remove) new tools without upgrading the main Geopsy frame.
The advanced signal processings tools are available under the menu Tools or directly by clicking on the icons in the toolbar. The following 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 as a function of azimuth in the horizontal plane
- H/V spectral ratio : Horizontal-to-Vertical spectral ratio
- H/V Rotate : Horizontal-to-Vertical spectral ratio as a function of azimuth in the horizontal plane
- Noise reduction
- Particle motion
- Refraction with NA: obsolete
- Time frequency analysis
- Structure spectrum
