Abstract：Inthis paper，theuseof airborne sonarunderdepsea conditionsis studied.Thesonardetectiondistance model isestablishedbyusing thesonarequation.Basedontheanalysisof thestructureandvariationcharacteristicsofthedep-sea soundvelocityprofile，theunderwatersoundfielddistributionunderdiferentdeep-seasoundvelocityprofilestructuresand diferentsonardetectiondepthsissimulatedbyusing therayacousticmodel.Thesubmarine'sactivitylawisanalyzed，and therelationshipbetweenthesonarworkingdepthandtheaveragedetectiondistanceisobtained.Theresultsshowthatunder deepseaconditions，theincreaseof theworkingdepthoftheairbornesonarisbeneficialtothedetectionofunknowndepth targets.The research results have guiding significancefor guiding theuse of aerial sonar in deep sea conditions.
