Abstract
This article considers the problem of estimating the delay difference and doppler frequency difference for the arrival of a white noise signal from a distant Quasar at two widely separated receiving stations on Earth. The nonlinear Barankin bound is reviewed as it applies to the very long baseline interferometry (VLBI) problem, and used to evaluate the signal-to-noise ratio threshold for VLBI Estimates. We conclude by comparing the performance of several sampling strategies for VLBI data.
