Abstract：We propose in this paper an adaptive matching predictive filtering vibroseis harmonics suppression method based on least squares theory.First we use the phase shift method to separate harmonics from ground force fundamental.Then we construct an adaptive matched filtering operator and match predicted harmonics to true harmonics with iterations of least square idea.Tests on numerical and field data show that the proposed method can suppress harmonics without effective energy loss,which confirm correctness of the proposed method.
