Study on Noise Removing by Wavelet Transform for Dynamic Measuring of Ship Magnetic Field

动态测量是舰船磁场测量中的重要方式,针对舰船磁场动态测量中的噪声特点,采用小波变换技术进行了消噪处理。仿真结果表明,小波变换技术可以较好的消除各个频段的磁场噪声,较好的恢复原始舰船磁场信号,在实际舰船磁场动态测量中有重要的应用价值。

Dynamic measuring is an important method for ship magnetic field measuring.According to the character of the noise in the dynamic measuring,wavelet transform was used to remove the magnetic noise.The simulation result showed that the wavelet transform technology can remove the magnetic noise in each frequency completely and the original magnetic signal of the ship can be rebuilt well,which has important application value in the actual dynamic measuring for the ship magnetic field.
