摘要Mathematically, there exist an effective transformation relationship between the electromagnetic (EM) and virtual seismic data fields, by which one can effectively to identify the underground target's interfaces using the EM method. Such transformation is a uncertain problem, which can be treated by the singular value decomposition (SVD) method. Because large singular values control main information of inversion matrix, small singular values are usually less important. So one usually ignores small singular values during singular value decomposition caluculation, leading to low precision results. To solve this problem, a new algorithm named the modified truncated singular value decomposition method was proposed, in which the ridge estimation method is used to calculate the virtual wave field caused by small singular values. The results of model calculation show that the improved truncated singular value method is better than the traditional singular value decomposition method. Using this new method, the survey data from a gob area of a coal mine was processed, and the interface of this area was successfully identified.
