Ultra Short Baseline Acoustic Position Method Based on the Multi-array-elements Base

The base size of traditional ultra short base line acoustic position system is very small.It is unable to assert the long-range target accurate position,which becomes a bottleneck of the further application of the ultra short base line position system in the domain of underwater sound navigation.Therefore,this article discusses the method of the multi-array-elements base to improve the system position accuracy,and has proven the feasibility of this method through the computer simulation.
