The selection of technical parameters for the vibroseis affects considerably the quality of the seismic data acquired from seismic exploration. The Matlab GUI design was adopted to simulate the influence of various parameters (such as scanning signal type, frequency range, signal phase shift and amplitude distortion) on the signals produced. The change of the parameters of scanning signal in the graphic interface can be conducive to the comparison and analysis of vibroseis scanning signal simulation waveform under the condition of different parameters.
