基于相位干涉儀陣列多組解模糊的波達角估計算法研究
A Multi-pare Unwrap Ambiguity of Interferometer Array for Estimation of Direction of Arrival
-
摘要: 該文針對利用相位干涉儀估計波達角過程中的相位模糊的問題，提出了一種利用多個相鄰陣元之間的相位差以及它們的間距比進行多組解模糊的方法，并且分析了這種方法得到正確波達角估計值的條件。仿真試驗驗證了上述結(jié)論的正確性。

Abstract: 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. -
