Radio Astronomy with the
21 cm Hydrogen Line at the
International Space University
Joachim Köppen Strasbourg 2011
These notes are a collection of of our experiences with doing radio astronomy
in the 21 cm spectral line of atomic hydrogen.
They contain the descriptions of our system, the experiments that we did as well
as the procedures that we went through, results and findings, explanations and
suggestions how to do this kind of enterprise.
The material presented here we use for our students, and we hope that they are
also helpful for others interested in this subject, especially for future users
of (what we named) the ESA-Haystack radio telescope.
This Website will always enjoy modifications ... ;-)
