  • Short window norm optimization for multi-source multi-component seismic data
    Patent number: 5657294
    Abstract: A method for processing multi-source multi-component shear wave seismic data. The method comprises the steps of: acquiring four component shear wave seismic data; converting the data into a matrix that is a function of an angles of rotation relative to a reference axis; computing a time independent norm of the elements of the matrix; and finding the angles of rotation where the difference between the sum of the norms of the in-line elements and the sum of the norms of the cross-line elements is maximized.
