Processing of magnetometric data during remote diagnostics of underground steel pipelines
For processing of magnetometric signals during remote diagnostics of underground steel pipelines, parametric wavelet functions of algebraic type were applied. It made it possible to reduce in several times the level of random noise and to improve significantly trustworthiness of evaluation of the stress-strain state of the underground steel pipeline metal.
