Abstract
Summary
A novel acoustic wave-equation-based full-waveform source location method is proposed to locate sources independently and accurately. With carefully data pre-processing and source-independent inversion strategy, source location parameters can be isolated from others and can be retrieved accurately even when origin time and source signature are inaccurate. Based on acoustic wave-equation, new Fréchet derivatives of waveform with respect to location parameters is derived. 3D numerical examples are presented to demonstrate the validity and high efficiency of the proposed method. Finally, field data are used to show the realistic performance of the proposed method.
