分析了鱼雷转速信号产生噪声的原因。应用FIR数字滤波方法、离散维纳滤波器方法及小波消噪算法对测试信号进行消噪处理并比较了3种方法的优缺点。
The cause of noise generated by torpedo speed signal is analyzed. FIR digital filtering method, discrete Wiener filter method and wavelet denoising algorithm were used to denoise the test signal and the advantages and disadvantages of the three methods were compared.
