| 摘 要： | 针对超短基线的模糊度固定问题,该文提出了一种改进方法。该方法在长基线非线性约束模型的基础上,采用附加基线长度约束的模糊度搜索模型,该搜索满足基线长度的搜索函数最优解。实验结果表明,该文的算法与无基线约束模型、基线长线性约束模型的LAMBDA方法相比,模糊度成功率明显提高。

| Abstract: | Aiming at the ambiguity solution problem of ultra-short baseline,an improved method is proposed.On the basis of the long baseline nonlinear constraint model,the ambiguity search model with additional baseline length constraints is used to search for the optimal solution of the search function satisfying the baseline length.The experimental results show that the algorithm is compared with the ILAMBDA method without baseline constraint model and baseline linear constraint model,and the success rate of ambiguity degree is obviously improved. |
