基于海浪感应磁场模型的水下磁干扰补偿方法
A compensation method for marine submarine magnetic interference based on a wave-induced magnetic field model
摘要
Abstract
Aiming at low-frequency magnetic noise from seawater motion degrading measurement accuracy in marine underwater magnetic surveys,this paper proposes a compensation method to effectively suppress wave-induced magnetic interference.By analyzing the Weaver wave-induced magnetic field model,we improve the traditional T-L model and construct a TLW compensation model integrating carrier-induced and wave-induced interference.To address nonlinearity and uncertainty in parameter estimation,the Adam gradient-modified Black-winged Kite Optimization algorithm(BKA)is adopted to accurately solve the 20 compensation coefficients.Sea trial results show that compared with the classical T-L model,the TLW model significantty reduces the standard deviation of compensated magnetic data for both nearshore and offshore survey lines,with the improvement rate ranging from 19.7%to 31.6%.This study verifies that the proposed model and algorithm effectively enhance the anti-interference capability of sea-surface magnetic measurement systems,thus providing reliable technical support for high-precision marine geomagnetic detection.关键词
