Abstract:

     This paper employs infinite impulse response (IIR) digital filtering and Haar wavelet analysis to suppress the noise in the original ocean current velocity measurement signal. Experiments show that this method can improve the accuracy and stability of measurement results.

Key words: digital filtering, wavelet analysis, noise, ocean current velocity
