【摘要】：海洋磁场测量是海洋科学观测、海底资源勘探、国防安全等领域的基本手段之一。研究海浪等海水运动的磁场噪声机理、预测模型及抑制方法对于提高海洋磁测精度具有重要的意义。该文在分析一阶Stokes波浪运动方程的基础上,提出一种改进型的海浪磁场模型,并推导出深海和浅海条件下的简化公式。为了验证模型的有效性,在2015年第15号台风"天鹅"过境期间,对我国南海某海域的海洋环境磁场进行了观测,并将该文模型和经典的Weaver模型分别与测试结果进行了对比。结果表明,该文提出的改进型模型能够更加准确地预测海浪磁场大小,预测精度比Weaver模型提高了近一个量级,可为海洋磁场测量的噪声抑制提供一种更加有效的工具。
[Abstract]:Marine magnetic field measurement is one of the basic methods in marine science observation, seabed resource exploration, national defense security and so on. It is of great significance to study the mechanism of magnetic field noise, prediction model and suppression method of ocean wave and other sea water motion for improving the accuracy of ocean magnetic measurement. Based on the analysis of the first order Stokes wave motion equation, an improved wave magnetic field model is proposed, and a simplified formula for deep-sea and shallow sea conditions is derived. In order to verify the validity of the model, the magnetic field of marine environment in a certain sea area in the South China Sea was observed during the transit of Typhoon Swan No. 15 in 2015. The model and the classical Weaver model were compared with the measured results. The results show that the proposed improved model can predict the wave magnetic field more accurately, and the prediction accuracy is nearly one order of magnitude higher than that of the Weaver model. It can provide a more effective tool for noise suppression in marine magnetic field measurement.
