| Abstract: | In accordance with the waveform characteristics of the array full wavetrain acoustic compo-nent wave,a signal detection model adapting to the characteristics has been constructed. And amethod based on wavelet transform has been raised for detecting the signal arrival. By using themethod, we precisely implement the extraction of signal arrival for the real marine array full wavetrain acoustic log. |
