【Abstract】 The data acquisition technique for single-channel seismic survey was systematicly reviewed in this paper in order to improve the resolution of single-channel seismic profiles and enhance the signal/noise ratio.Based on our experience in practice and sea testing under various boundary conditions,such as different sources,different regional background of noise characteristics and different receiving hydrophones,we proposed a feasible data acquisition system in this paper for single-channel seismic survey.High resolution and high signal/noise ratio may be achieved through the new system.更多还原
