Interferometers with bandwidths of 384 and 50 MHz have been constructed using the Mk IA and Mk II telescopes at Jodrell Bank. Both systems use an analogue by single-bit digital correlation scheme and are well suited to rapid measurements of the flux densities of weak sources. The wide-band interferometer has been used to observe sources at the 30 μJy level using a mapping technique which is particularly relevant to studies of the cosmic microwave background radiation. The high sensitivity of these systems makes them ideal for rapid measurements of the surface profiles of the telescopes as a function of elevation.
