Abstract

Abstract

In view of the increasing application demand of underwater collaborative operation of divers, based on the traditional ultrashort baseline positioning technology, an underwater positioning and direction-finding technology scheme on the micro ultrashort baseline tetrahedral receiving array is designed for underwater operation of divers. In view of its direction-finding ability, the simulation analysis is conducted on the factors that affect the direction-finding accuracy caused by the complex underwater acoustic channel characteristics, especially multipath, the phase difference between different elements of the receiving array that is difficult to calibrate by conventional means, and the unsteadiness change of the divers’ underwater operation posture. The simulation results show that the positioning and direction-finding technology scheme is feasible and can meet the application needs of divers to obtain mutual position information during underwater collaborative operations.
