| 摘 要： | 结合次声波的特点和性质，建立了适用于动态环境下的基于次声波和电磁波的非同步TDOA测距模型。同时，将精确的测距信息与历史位置信息结合起来，提出并推导了信标节点稀疏分布下的三维测距解析定位算法，并根据有限的定位时刻位置信息采用内插法恢复出节点随机运动轨迹图。仿真结果表明：该算法具有较好的鲁棒性，可实现分米级以下的定位精度。 |

| Abstract: | Combined with the characters and properties of infrasound, an asynchrony TDOA （ Time Difference of Arrival） ranging model based on the infrasound and the electromagnetic signals and suitable for dynamic circumstances is proposed in this paper. At the same time, by combining the accurate ranging data and historical location, a three-dimensional ranging and analytic locating arithmetic with neighboranchor-node-deficient is proposed and deducted. In addition, the track of the random-movement is reappeared form the limited known positions by the interpolator method. Finally, the simulation results show that the method is robust and the accurate locating less than a decimeter can be realized. |
