| Abstract: | It is relatively difficult that the pulse position information is detected exactly in shallow water acoustic channels,which has to overcome the severe interference coming from strong multipath,large fluctuation and high noise.The main characteristics of fluctuation for signal amplitudes and repetition periods,and their effects on detection of the pulse position infonmation are analysed .The possible ways to overcome signal fluctuation are proposed.The discussed contents in the present work are of referenca value to other mode of signal detection in principle. |
