摘　　要：提出了用奇异值分解(SVD)原理直接估算多道地震记录能量信噪比的方法。此方法适用于水平同相轴地震记录及共炮点(或共中心点)地震记录的能量信噪比估算。采用合成资料试算结果表明,其估算值与理论值吻合较好。SVD(singular value decomposition) method has been presented by which the ESNR(energy signal-to-noise ratio) of multitrace seismic data can be estimated directly. This method is applicable to estimating the ESNR of horizontal events and common-source point (or common midpoint) seismic date. The ESNR of calculation with synthetized data shows that the result matches well with the theoretical values.
