Abstract：During parameter tests for seismic data acquisition in the field,source parameters determination are made mainly through qualitative quantitative analyses to frequency scan,energy,signal to noise ratio or frequency spectrum.Analysis results are often different because of different analyzers.The paper discusses parameter optimizing on the following assumptions: with repeated shootings at the same position,receiving with the same spread and same wavelet phase of different shots,and adopting correlation theory,correlations of seismic data with different source parameters are analyzed.Then the optimum source parameters are determined by comparing the correlation coefficients and stack correlation coefficients.Finally application examples are given.
