Abstract—Three-element array is often used for measuring the distance between the object and the reference element. Cooperating with other devices or increasing the number of elements, the three-element array may achieve 3D (3D: three-dimensional) passive position. To the problem of 3D passive position of three-element array, this paper provides a method achieving three-dimensional passive position based on the underwater acoustic channel propagation characteristics in 0~359° . At the same time, the method can solve the y-axis fuzzy direction of the linear three-element array without prior knowledge. The numerical analysis and simulation show that this paper can well complete three-dimensional passive position, especially for the shallow water short-range target. 

Index Terms—three-element array, underwater acoustic channel, three-dimensional passive position
