| 英文摘要 | Non-uniform sampling fast Fourier transform (NFFT) is a method for efficient spectrum calculation of nonequispaced data. It's the fundamental algorithm of reconstruction techniques by spectra estimation of irregularly sampled signals. High efficiency and precision is the key for its application. In order to achieve high performance for 2-D cased I utilize table-riven techniques to reformulate Gauss convolution operator into elliptic form to reduce numerical operations and substitute exp function by multiplication operation to accelerate computing efficiency. I also create several tables to introduce NFFT to seismic data processing. Based on these works I explain how to reconstruct nonuniform sampled seismic data via 2-D NFFT. At last three numerical experiments are shown to illustrate computation speed, calculation accuracy and reconstruction results for irregular sampled seismic data respectively. |
