Introduction to Very-Long-Baseline Interferometry,

Abstract

Long baseline interferometry achieves high angular resolution by using two (or more) widely separated radio telescopes and recording video signals on magnetic tapes, which are later brought together and cross-correlated. This paper contains discussions of the coherence and timing requirements, and of calibration procedures. Applications to measuring brightness distributions and to spectroscopy are reviewed briefly. Some pertinent phenomena connected with radio wave scattering in irregular media are discussed. (Author)
