Rule seeks to detailed system the relationship between seabed backscatter intensity and sediment types feature, discloses different sediments
It is to carry out backscatter intensity data bottom to the statistic correlation of acoustic signals frequency variation to establish substrate acoustic concerns model
The ideal method of matter classification of type theoretical foundation.And Seafloor Classification acoustics sink and experimental method are rarely reported.
Acoustics water column information carries the complete acoustic signal from energy converter to seabed, is target in water（Including gas and
Solid）Backscattering imaging after by insonify.Acoustics water column Detection Techniques can be widely applied to underwater object（Submarine mine is dived
Ship）The military civil fields such as identification, suspended load transport, gas leakage, submarine hydrothermal solution spout, internal wave of ocean.Due to acoustics water column
Detection is still a kind of new detection means, also less to its research at present, and is lacked to acoustics water column information and acoustic scattering
The research of relationship model.
