Abstract
This article gives a tutorial presentation of the basic principles underlying Very Long Baseline Interferometry (VLBI) using bandwidth synthesis. Although many subtle details are ignored, the article presents the basic signal processing approach and summarizes results showing the tradeoff of measurement accuracy with spanned bandwidth, source strength, antenna size and efficiency, system noise temperature, and data volume. Results pertaining to minimization of required antenna time for a given baseline measurement accuracy are also discussed.
