| 摘 要： | 针对相位干涉仪测向工程实现中遇到的通道间连接电缆不等长和通道隔离度不够引起同频干扰的问题,从理论上分析这2种影响因素对测向相位差误差的影响,在工程可实现基础上,推导不等长、通道隔离度与相位误差的数学关系,为相位干涉仪设计和通道误差校正提供理论依据。

| Abstract: | In the process of phase interferometer direction finding project implementation,different connecting cable length and insufficient channel isolation are the main factors that cause the same frequency interference.The influence of these two factors on the phase difference is analyzed theoretically.On the basis of engineering realization,the numerical relations between unequal length,channel isolation and phase difference are derived,which provide theoretical basis for the design and channel correction of phase interferometer. |

| Keywords: | phase interferometer unequal cable length channel isolation |
