| 摘 要： | 不同类型的射电望远镜阵的分辨率差异甚大，用它们的数据进行图像处理后所得到的源结构的尺度也不一样。为了得到中间尺度的结构信息，有时我们需要把不同类型的射电望远镜阵的观测数据结合起来再进行图像处理。本文阐述我们把不同类型阵的数据结合时所用的方法；也给出我们使用的方法所获得的结果的实际例子。

| Abstract: | The resolving powers of existing telescope arrays are quite different. This means that images obtained with these instruments yield maps on different scales that sometimes appear unrelated. However, the need to have structral information on intermediate scales demands that data from different arrays be combined to make a single image. The paper presents the basic principles for combining the data obtained with different arrays, and also shows us several images of extra-galactic radio sources mapped with combined data. |
