| 摘要: |
| 为了进一步提高海洋环境下无线传感器阵列网络（UWSAN）对被动目标三维定位的可靠性和定位精度，在推导多节点网络基于到达时间差（TDOA）定位和基于波达方向（DOA）定位的基础上，应用最小二乘原理，提出适用于UWSAN的TDOA-DOA多模态信息融合定位算法。通过计算机仿真将该信息融合算法与TDOA方法和DOA方法进行比较，结果表明，相对于单模态信息的定位算法，多模态信息融合算法的定位误差更小，性能更加稳定和可靠，具有实际的应用价值。 |

| Abstract: |
| We propose a new approach to improve the system reliability and positioning accuracy of underwater wireless sensor array network (UWSAN) based on multi-modal information fusion. In section 0, we analyze the inadequate of traditional single-mode target localization methods. In section 1, TDOA and DOA location algorithm adapted to multi-node network are deduced respectively, laying the foundation of multi-modal information fusion. In section 2, TDOA and DOA are fused by the principle of least square(LS) to get a novel passive target location algorithm, which we believe is effective. In section 3, simulations are performed to compare the positioning performance between information fusion algorithm, TDOA method and DOA method; the results, given in Fig.3 through 6, and their analysis show that our new approach based on multi-modal information fusion for multi-node UWSAN can indeed reduce the positioning error and enhance the robust of UWASN, which has a practical application value. |
