基于改进EMD算法的水下潜艇磁异常信号处理分析
Analysis of Underwater Submarine Magnetic Abnormal Signal Processing Based on Improved EMD Algorithm
摘要
Abstract
The detection of signals is a key part of underwater submarine magnetic anomaly detection.In order to deal with the phenomenon of modal aliasing existing in the traditional EMD algorithm,this paper simulates the classical magnetic dipole model of submarine magnetic anomaly signal.The improved EMD algorithm is used to detect the simulated signal in high noise environment. The test results show that this method has strong self-adaptability and good completeness.It can restore the time-frequency charac-teristics of the target signal well in signal reconstruction.The result of this paper is of some reference to the development of the detec-tion algorithm of magnetic anomaly detection signal in underwater submarines in the future.关键词
