POTENCY TENSORS FOR SIMPLE AND EXTENDED SOURCES IN THE TIME DOMAIN

摘要：

Assuming a homogeneous medium and a point source, we perform lull-waveform potency tensor inversion in the time domain by linearisation. This method takes into account near-, intermediate- and far-field terms of the wavefield, and can also be used to invert for simple extended sources. The method is tested on synthetic examples where the source mechanism and directivity effects are prescribed and can be qualitatively compared with inversion results.
