Embodiment Construction
[0055] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0056] A method for reducing random noise of full-wave magnetic resonance signals by combining EMD and TFPF algorithms, comprising the following steps:
[0057] a. Perform EMD decomposition on the full-wave magnetic resonance observation signal X(n) collected by the nuclear magnetic resonance groundwater detector (n is a discrete sample point), and decompose i different eigenmode components C from high frequency to low frequency 1 (n),...,C i (n) and a trend term R i (n), X(n)=C 1 (n)+L+C i (n)+R i (n);
[0058] b. For the eigenmode component C 1 (n),...,C i (n) and the trend term R i (n) Carry out Fourier transform and autocorrelation analysis, synthesize Fourier transform results and autocorrelation analysis results to obtain noise-dominated modal components and signal-dominated modal components, and extract signal-dominated modal components c ...
