Quarter 3: Principles of Interferometry | Hans-Rainer Kloeckner
Radio Interferometry and Synthesis Imaging is the art to synthesise a very large effective aperture from a number of "smaller" antennas. Combining the signals of these antennas will result in a meaningful property that can be used as a diagnostic tool to investigate the original state of the received radio waves.
In this light the lectures will explain the theory and the technical requirements needed to successfully measure extraterrestrial radio emission.
