It is first time paper that the planar wave decomposition both for spherical harmonic wave and for impulsive wave has been theoretically discussed the article analyzed the relation between present τ p transform and spherical wave decomposition,put forward a exact decomposition method for spherical impulsive records and gave a numerical example. The results of theoretical analysis and numerical test show that simple τ p transform can't truly realize a planar wave decomposition for spherical wave,the method presented in the paper can better resolve the problem of spherical wave decomposition.
