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.%针对海流测量中的噪声问题,采用无限脉冲响应数字滤波及Haar小波分析方法,通过对原始信号的处理,去除其中的噪声。实验证明,该方法可以提高测量结果的稳定性及准确度。
