LAMBDA方法中最佳双差模糊度选择问题研究

Study on Selecting Problem of the Optimum Double-Difference Ambiguity in the LAMBDA Method

从双差模糊度的定义出发 ,分析了双差模糊度组合的几种常用方式 ;接着给出了判断模糊度方差 协方差阵结构好坏的标准 ;最后用一个实例具体比较了不同双差模糊度组合时模糊度方差 协方差阵的相关性及其对模糊度搜索效率的影响 。

Several typical combinations of double-difference ambiguities are analyzed from the definition of the double-difference ambiguity. After that, some criteria are given for judging the construction of double-difference ambiguity variance and covariance matrix. At last, an example is given to illustrate the views put forward in this paper and the optimum combination of double-difference ambiguity for high efficiency of LAMBDA is given out.
