摘要
在证明了多基线的相位干涉仪不产生测向模糊的充要条件后,讨论了两种用长基线组合解测向模糊的算法.通过对存在测量误差情况下正确解模糊条件的分析,提出了避免错误解模糊的方法.对两种算法的解模糊容差的比较,显示了两种方法的性能,为综合使用这两种方法提供了依据.文中的例子也有助于对多基线组合解测向模糊方法的了解.
After a sufficient and necessary condition of phase interferometer unambiguous direction finding is proved, two methods of ambiguity resolution by combination of long baselines are presented. In the presence of measurement error, the approach of correct ambiguity resolution is put forward after analyzing the condition. The comparison of two methods shows their performance, which can be used for system design. Some examples are given, which is beneficial to understand the ambiguity problem.
