摘　　要：针对多基线相位干涉仪测向时存在的相位模糊问题,分析相位差变化值的相位模糊特点,提出一种利用相位干涉仪基线间的参差距离对相位差进行解模糊的方法,讨论正确解模糊的条件、范围以及波达角估计精度与入射角之间的关系,并给出了仿真结果。For the problem of phase difference ambiguity using multi-baseline interferometers in direction finding, a new method is proposed for solving the phase difference variety ambiguity by stagger distance difference after the analysis of the phase difference. The conditions, range and the relationship between the angle of incidence and the estimation accuracy of direction of arrival are discussed. At last, the simulation results are given.
