| Abstract: | In two-dimensional leakage magnetic testing system, disturbance amony flaw signals from lon- gitudinal sensor array is inevitable. The method of relative gradient algorithm contained in blind source separation was employed to reduce the disturbance between flaw signals. The experiment results show that this method is steady in reliability and validity and improves the performance of the detected equipment. Thus blind source separation has great potential in flaw signals process. |
