摘要
针对海浪产生的磁场信号对海洋微弱磁信号检测影响较大的问题,利用Weaver理论建立海浪产生电磁场噪声模型作为研究对象,并通过基于最小均方(LMS)算法的自适应滤波器对探测磁场进行处理,能有效滤除海浪磁噪声,检测出微弱磁信号,达到了滤除海浪磁场噪声的目的。
The wave-generated magnetic noise have a great impact on ocean weak magnetic signal. Building a model of wave-generated magnetic noise based on Weaver 's theory. Filtering the detected magnetic signal based on LMS adaptive filter from the model. The wave-generated magnetic noise could be removed well and the weak magnetic signal could be detected.
