摘要：

We report the first observations of the cosmic microwave background radiation (CMBR) at 13.5 GHz made with the Cosmic Anisotropy Telescope (CAT) near Cambridge. After removal of foreground ra;iia sources brighter than 10 mJy using the Ryle Telescope (RT), the map shows evidence for residual structure on a scale of approximately 1/2 degrees with an rms variation of 18 mJy. We intend to use multifrequency measurements to distinguish between Galactic and CMBR components.
