| 摘 要： | 在相位干涉仪测向系统中，通常都认为基线倾角对相位的影响是可以通过几何投影的方法得到等效基线来消除的．针对基线倾角的存在，从相位干涉仪测向原理出发给出了定性的分析，指出了基线倾角给相位干涉仪测向系统带来的测角错误，并通过实验的方法证实了其分析的正确性，在实际工程应用上具有一定的指导意义．

| Abstract: | In the system of measuring angle of phase interferometer, it is considered that the impact brought by baseline obliquity on phase can be eliminated by equivalent baseline from geometric projection. In view of the existence of baseline obliquity, the paper gives a qualitative analysis according to the theory of measuring angle by phase interferometer, puts forward the mistake of measuring angle brought by baseline obliquity in the system of measuring angle by phase interferometer and proves the correctness of the analysis by experiment, providing instructional significance in the application of the actual engineering projects. |
