Application_study_of_wavelet_analysis_on_ultrasoni
说明: :在深海采矿环境中超声波传输介质里存在着大量气泡、扰动沉积物、机械噪声等背景噪声与混响,导致有用信号与高
噪声信号迭加在一起,严重影响了测距精度。采用小波分析方法将超声回波信号进行3层小波分解,适当设置门限阈值对小波
系数进行处理,然后对信号进行重构,有效地抑制了信号中噪声对测量精度的影响。研究结果表明:小波方法有很好的降低回
波信号中噪声的效果,其测距精度高于自适应滤波去噪后的测距精度。(There are much background and mixture noise in the course of ultrasonic wave transmission under deep
sea mining environment,such as air bubbles and disturbed sediment and mechanical noise.Because of these factors,
the useful signals and the high noise signals are combined together,which seriously affects the distance measurement
precision.Ultrasonic echo signals are decomposed into three layer wavelets,and a threshold is set to process the
wavelet coeficients.Then the signals are reconstructed.Accordingly the influence of environment noise on distance
measurement precision is effectively restrained.Research resuhs indicate that wavelet transform method is very useful
for noise reduction in signals.Its precision is higher than that of the adaptive filtering method.)
