Its principle is already known, but it has been seldom used in seismology. We have re-examined this method a little more in detail. Sets of experimental signals have been used to test the technique. Tests using synthesized seismograms have proven the usefulness of this method if appropriate corrections are taken into account. However, as for the actual seismograms recorded at our array stations, the calculated data tend to scatter considerably as the period increases or decreases. With respect to accuracy, our tests suggested no superiority of this method over the conventional phase comparison method. This seems to be inconsistent with the conclusions of former authors(DZIEWONSKI et al., 1968 ; LANDISMAN et al., 1969).", "subitem_description_type": "Abstract"}, {"subitem_description":
