Extract

The arrangement whereby the front end of a radio astronomical receiver is located at the focal plane of a paraboloidal telescope causes the incoming waves to be reflected between focal plane and vertex. The result is a sometimes simple, sometimes complex wave pattern on the output of an associated spectrometer and is known as baseline ripple.
