| 英文摘要: |
| Three-element array is often used to complete the task of surveying the distance between the object and the reference element. To achieve three-dimensional positioning, cooperation with other devices or increasing the number of array elements are requried when using three-element array. In allusion to the problem of three-dimensional positioning of three-element array, this paper shows a method to achieve passive three-dimensional positioning based on the underwater acoustic channel propagation characteristics. At the same time, the non-linear three-element array in this paper can solve the linear three-element array ambiguity around the y-axis direction. The numerical analysis and simulation show that this paper can well complete three-dimensional positioning of three-element array, especially for the shallow water target. |
