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 . 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 ar rival by using the second-order of the phase of interferometer array.The possib ility of correction is analysed.The conclusion is supported by simulation result s.
