The Measurement of Polarization in Radio Astronomy

  title={The Measurement of Polarization in Radio Astronomy},
  author={Timothy Robishaw and Carl Heiles},
Modern dual-polarization receivers allow a radio telescope to characterize the full polarization state of incoming insterstellar radio waves. Many astronomers incorrectly consider a polarimeter to be the “backend” of the telescope. We go to lengths to dissuade the reader of this concept: the backend is the least complicated component of the radio telescope when it comes to measuring polarization. The feed, telescope structure, dish surface, coaxial cables, optical fibers, and electronics can… CONTINUE READING
