| 摘 要： | 为减小地震数据缺失给地震后续处理工作带来的影响，需要对地震数据进行插值重建.针对反假频插值重建这个难点问题，进行了相关研究，并由此提出了一种改进的R-P（半径-斜率）域加权反假频地震数据插值重建方法.该方法将F-K（频率-波数）谱变换到R-P域，在R-P域设计一个权函数并将其作用于每次的迭代插值过程.通过模型数据和实际数据的测试，证明了该方法具有较好的反假频插值重建能力.

| Abstract: | In order to reduce the influence of the missing seismic traces on the follow-up seismic processes, seismic data reconstruction is required. To solve the problem of anti-alias seismic data reconstruction, some research about this was done and a new method called weighted anti-alias seismic data reconstruction in R-P (radius-slope) domain is proposed. The F-K (frequency-wave number) spectra are transformed to the R-P domain and a weighting function is designed. During every iteration process of the reconstruction, the R-P spectra are modified by the weighting function. By testing with synthetic and field data, the capacity of anti-alias reconstruction of this method is proved. |
