A spectral synthesis method to suppress aliasing and calibrate for delay errors in Fourier transform correlators
Tak Kaneko, Keith Grainge
Context: Fourier transform (or lag) correlators in radio interferometers can serve as an efficient means of synthesising spectral channels. However aliasing corrupts the edge chann…
Implementation of an Optimised Cassegrain System for Radio Telescopes
C. M. Holler, R. E. Hills, M. E. Jones +2
We present the antenna design for a radio interferometer, the Arcminute Microkelvin Imager, together with its beam pattern measurement. Our aim was to develop a low-cost system wit…
AMI limits on 15 GHz excess emission in northern HII regions
A. M. M. Scaife, N. Hurley-Walker, M. L. Davies +13
We present observations between 14.2 and 17.9 GHz of sixteen Galactic HII regions made with the Arcminute Microkelvin Imager (AMI). In conjunction with data from the literature at…
A 6-12 GHz Analogue Lag-Correlator for Radio Interferometry
Christian M. Holler, Tak Kaneko, Michael E. Jones +2
Aims: We describe a 6-12 GHz analogue correlator that has been developed for use in radio interferometers. Methods: We use a lag-correlator technique to synthesis eight complex spe…
