What is the purpose of heterodyning in radio astronomy?!
I'm aware that heterodyning is a radio signal processing technique as kindly explained by the Wiki article on the topic (http://en.wikipedia.org/wiki/Heterodyne).
However I don't understand how radio astronomers use this technique to aid their observations, what sort of analysis can they do with f1-f2 and/or f1+f2?
Thank you in advance,

Do you know whether heterodyning involve any advantages to processing the data since the technique lowers the frequency?
