摘要
讨论地震波反演问题中顾及测量误差的重要性,分别采用LSQR、WLSQR和MLS的方法对含有误差的地震波模拟数据进行了反演,结果表明地震面波反演问题中测量误差的影响显著,忽略测量误差的影响将大大降低反演结果的可靠性。
Importance of observation' s error in seismic inversion was discussed, and the seismic wave simula- tion data that contains error were inversed using methods of LSQR, WLSQR and MLS. The inversion results show that the effect of observation' s error is notable in seismic surface wave inversion , and ignoring the observation' s er- ror will greatly reduce the reliability of inversion results.
