我们提出了一种用于分析宇宙微波背景各向异性和偏振的干涉观测的形式。这种形式是基于近些年流行的角功率谱的ℓ空间展开。给出了最大似然分析、功率谱重构、参数估计、成像和极化的详细讨论。作为例子，给出了度角尺度干涉仪和宇宙背景干涉仪实验的几种计算方法。
We present a formalism for analyzing interferometric observations of the cosmic microwave background anisotropy and polarization. The formalism is based on the ℓ-space expansion of the angular power spectrum favored in recent years. Explicit discussions of maximum likelihood analysis, power spectrum reconstruction, parameter estimation, imaging, and polarization are given. As an example, several calculations for the Degree Angular Scale Interferometer and Cosmic Background Interferometer experiments are presented.
