Abstract： By analyzing the fault mechanism of abnormal data of the depth sounder on platform，and combining acoustic principles with signal processing technology，this paper proposes a targeted software optimization scheme.The optimization measures include the use of linear frequency modulation （LFM） algorithm，adjustment of the transmited signal pulse width，optimization of botom tracking algorithm，etc.，and finally solved the problem of instability of bathymetry data display through real ship verification， which provided an important reference for the adaptability optimization of the sounder in special ship environment.

Key words： depth sounder; acoustic principle; signal processing; environmental adaptability
