Abstract：Based on the scanning signal parameters which are used in Vibroseis seismic acquisition,the Vibroseis scanning signal was calculated,then Vibroseis zero phase wavelet was derived from auto-correlation of Vibroseis scanning signals. Then by utilizing the Vibroseis zero phase wavelet the conversion operator which converts the zero phase wavelet to minimum phase wavelet was derived. At last the conversion operator is used to convert the Vibroseis zero phase wavelet to minimum phase wavelet so that the function with which the seismic records with Vibroseis zero phase source wavelet are converted to seismic records with minimum phase source wavelet is realize
