基于化极和VMD融合的海底电缆航磁探测方法
Aeromagnetic detection method for submarine cables based on fusion of reduction to the pole and VMD
摘要
Abstract
Aiming at the problem that the magnetic anomaly signal of submarine cable is difficult to detect in complex marine environment,a method for extracting and identifying the magnetic anomaly signal of submarine cable based on frequency domain polarization and variational mode decomposition(VMD)is proposed.Firstly,the oblique magnetization signal is transformed into a vertical magnetization signal by frequency domain polarization.Then,VMD is used to decompose and reconstruct the polarized signal,and the cable magnetic anomaly signal buried in the background noise is extracted for identification.In order to verify the effectiveness of this method,the recognition results are compared with the detection results of the pipeline detector.The deviation between the identification results of this paper and those from the pipeline detector ranges from 0.64 m to 7.20 m,with a root mean square error of 4.17 m.This demonstrates the effectiveness of the proposed method in accurately locating subsea cables.关键词
