A Novel Method for De-nosing in Marine Magnetic Survey
Xiao Fumin · 2009
Wave noise and random noise are remarkable factors in influencing accuracy of processing of marine magnetic survey. Based on the basic theory of wavelet threshold,a method of de-nosing is presented to improve the precision of de-noising.Simulation and practical results shows that,by using wavelet decomposition and reconstruction,the method can efficiently remove wave and random noise of data.Moreover,compared with classic processing techniques,it has excellent accuracy and reliability.The method has solved localized problem of noise and real high frequency information in data is filtered with traditional slide fitting method.
