摘要 |
An unconstrained transformation filter operator that is efficient in terms of computer resources and that improves circularly symmetric migrated impulse response for steep dips. The filter operator combines 5 selected desirable attributes of the more efficient McClellan transformation filter with selected desirable attributes of the more accurate Laplacian transformation filter. The novel filter operator is not constrained along the k x and k y spatial axes by the requirement that it equal cos(k). The transformation filter is averaged over all azimuths to improve its accuracy of response. |
