Source wavelet estimation

The autocorrelation of seismic signals can provide some preliminary information about the source. 

The code SOURCE_WAVELET_ESTIMATION.m was written to auto-correlate two files of seismic data in Segy format (synthetic_data1.segy and synthetic_data2.segy). The source wavelet is estimated based on the autocorrelation, and its amplitude and phase spectra can be found in the folder.  The estmated source can be found in the folder SOURCE_OUTPUT_FILE.
