摘　　要：介绍了相位干涉仪测向系统相位误差产生的原因,针对因通道不一致性导致的相位误差提出了一种消除方法。着重分析了基线倾角的存在引起的相位误差,经分析得出当倾角不为0时,相位函数不再是一条直线,误差的大小与入射角有关。给出了相位差和基线倾角的对应关系,并在实际系统中证实了基线倾角的存在产生的相位误差对整个测向系统的影响。The reasons of the appearance of phase error in the system of direction finding by phase interferometer are introduced and a method of eliminating phase error resulted in inconsistency of channels is put forward. The phase error brought in baselines＇ obliquity is analysed specially and the connection to phase difference and baselines＇ obliquity is proposed. The impact on the system of direction finding for the existence of baselines＇ obliquity is approved in actual system.
