A Multi-pare Unwrap Ambiguity of Interferometer Array for Estimation of Direction of Arrival

该文针对利用相位干涉仪估计波达角过程中的相位模糊的问题,提出了一种利用多个相邻阵元之间的相位 差以及它们的间距比进行多组解模糊的方法,并且分析了这种方法得到正确波达角估计值的条件。仿真试验验证了 上述结论的正确性。

In the background of phase ambiguity in using phase interferometer to estimate the direction of arrival, a new method is proposed for estimation direction of arrival by using interferometer array with the algorithm named as multi-pare unwrap ambiguity. The possibility of correction is analyzed. The conclusion is verified by simulation result.
