| 摘要: |
| 本文对平面三站无源时差定位系统的定位过程中可能出现的无解和模糊现象进行了探讨, 找出了无解分布与布站以及观测噪声方差大小之间的规律, 得出了模糊分布与布站之间的关系, 并提供了一些解决方法。 |

| Abstract: |
| The problems of possible ambiguity and non-solution in 2D、3-Station TDOA Location systems are disscussed. We find out the relation between ambiguity and the placement of stations, and the laws of the placement of nonstation and the placement of stations、the intention of measuring noice. Furthermore ,We present several solutions. |
| Keywords: passive TDOA location, ambiguity, non-solution, the placement of stations |
