摘要
在四站无源时差定位中，当利用无迭代求解非线性方程组时，存在模糊与无解的问题，其模糊和无解区域与布站方式、目标高度和测量误差等有关。文章针对这一问题进行了仿真分析，讨论了在不同情况下，模糊与无解区域的变化和利用高度法去模糊的情况。
In the case of 4-stations passive TDOA location system, the ambiguity and non-solution problem are commonly existed when the non-linear functions are solving, and the problem is related with station position, height of target and measure error. Some simulation analysis about the problem is made in this paper. Variation of the ambiguity, non-solution area in different conditions and clear ambiguity by using height method are discussed.
