摘要

本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

提出了一种利用相位干涉仪阵列的相位差之差(二次相位差)得到长基线干涉仪的无模糊相位差并进行波达角估计的方法

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.

Abstract

In the background of phase ambiguity via using phase interferometer to estimate the direction of arrival

a new method is proposed for estimation direction of arrival by using the second-order of the phase of interferometer array.The possibility of correction is analysed.The conclusion is supported by simulation results.
