<p>A method for attenuating noise in seismic data signals is described wherein seismic signals are transmitted to the ground using a pseudo- random frequency sweep signal. Noise is then attenuated from the resulting, acquired seismic data before performing a process of phase-subtraction, e.g., before correlating or de-convolving the acquired seismic data. In this way, repetitions associated with, for example, diversity stacking techniques can be avoided.</p> |
