| 摘要: |
| 本文提出了一种利用多站TDOA信息对辐射源定位的非线性方程组求解方法, 该方法简洁准确, 无需作迭代运算, 计算量小。文中给出了该定位方法的精度分析, 最后给出了在具体布站条件下的受控区域内的GDOP分布。 |

| Abstract: |
| A new exact, explicit, uniterative, and computationally effcient solution of nonlinear equation set for estimation of emitter position based on the time differences of arrival (TDOA) measured by multi-stations is proposed in this paper. The accuracy analysis of the location method is also presented. Finally performance evaluation results of emitter location by using TDOA information are illustrated by some graphs of Geometrical Dilution of Precision (GDOP) under various conditions in the specific surveillance region. |
