The acute angle [theta] represents the angle between the ray direction from any imaging point and the principal polarization direction.
Taking the 3C seismic wave vector characteristics into account, the polarization migration technique suppresses false imaging by using the principal polarization vector on the basis of an amplitude value scalar stack.
The principal polarization direction can be calculated through a covariance matrix, which has a significant impact on the migration result.
The principal polarization direction can be calculated by using polarization analysis shown above.
With the principal polarization direction, the abnormal interfaces can be located accurately with polarization migration under small aperture.
