摘　　要：多基线相位干涉仪具有测向精度高、结构简单、观测频带宽的优点。为了解决多基线相位干涉仪的相位模糊问题,提出了一种基于余数定理的利用最长基线搜寻短基线相位的解模糊方法,并且分析了正确解模糊的条件。通过仿真验证了该方法的正确性。Multi-baseline phase interferometer had the merits of high direction finding（DF）accuracy,simple structure and wide observation band.In order to solve the phase ambiguity problem of multi-baseline phase interferometer,this paper proposes a solving ambiguity method using the longest baseline to seek for the short baseline phase which is based on the remainder theorem,and analyzes the conditions for correctly solving ambiguity,validates the correctness of the method through simulation.
