Abstract
This paper deals with the improvement of the calculation accuracy of derivation in the frequency domain and studies the stability and accuracy of the local wavenumber inversion result. A comparison of the calculation accuracy between the cosine function extending edge and the minimum curvature extending edge shows that the result of minimum curvature extending edge is higher than that of the cosine function extending edge. This paper proposes a technique which uses upward continuation to a certain height to acquire the local wavenumber inversion, which solves the high-frequency interference, improves the calculation accuracy of the derivation, and also obtains stationary inversion results that use different continuation heights, thus improving the accuracy of local wavenumber stationary. The precision of the technique was tested with numerical models. The authors have attained satisfactory results, as evidenced by the fact that the stabilization of the technique was proved by the real data processing.关键词
