because their polarization patterns are unique at the free-surface (except SH and Love waves)• Extract phase velocities and propagation direction• Extract the true incidence angle at the free-surface• Separate seismic phases that overlap in time
• Automatically distinguish between different wave types (P, SV, SH, Love, Rayleigh) because their polarization patterns are unique at the free-surface (except SH and Love waves)• Extract phase velocities and propagation direction• Extract the true incidence angle at the free-surface• Separate seismic phases that overlap in time
