FIELD: geophysical research, namely methods for removing noise from seismic data.
SUBSTANCE: method for processing seismic data includes such steps as: (a) determining the difference between the data in time window, which contains a part of first data segment, and the data in the corresponding time window which contains a part of second data segments, while aforementioned first data segments and aforementioned second data segment are selected from a set of data segments, registered during usage of a set of seismic sweep signals; (b) altering aforementioned data in first data segment when aforementioned data are used in corresponding time window, on basis of aforementioned difference.
EFFECT: suppression of, simultaneously, coherent noise, environmental noises and noises created by harmonics.
