摘要：
A method is described of reducing phase distortion in a detected seismic signal resulting from Doppler shifting of the transmitted signal. An operator is convolved with the seismic data to correct the dispersion. The operator is determined for the particular transmitted signal and boat speed. The operator is normally determined in the frequency-wave number domain. The seismic data may be transformed to the frequency-wave number domain for performing the convolution. The transformed data may then be transformed back to the time-space domain. Alternatively, the determined operator may be transformed to the time-space domain and the convolution performed in that domain.
