Abstract

Abstract:Basedontheminimum mean-squareerrorapproach,acomputationalmethodwasproposed forlocatingthepositionsofunderwaterexplosionsources.Theverificationexperimentsshowthatthe proposedlocationmethodcanmeetwiththetestrequirementswhenthequantityoftheeffectivedata observedbythepressuresensorsisnotlessthanfour.Satisfactorycomputationalresultscanstillbe obtainedeveniftheaccuraciesofseveraltestdataareweak.Theinfluencingfactorsofthecomputationalerrorwerediscussedasfollows: veracitiesoftestdata,positionturbulenceoftestpoints,accuraciesofmodelparametersandquantityoftestpoints. Consequently,somesuggestionswereputforwardaboutthelocationcomputationforunderwaterexplosionsources.
