Radio Telescope Question


Quote by toycoma View Post
Google the Itty Bitty Radio Telescope and build it. I did all thanks to Directv. Matter of fact i'm building a second one four miles away and linking them together via the internet. Talk about interferometry. Why didn't we think of this before??? Lol
This is not trivial to do because you will need to provide some common phase / timing reference for each half of the array if you want to make an interferometer. An interferometer only works if you can combine signals in a known relative phase. There is an unknown time delay on the internet so you would need to compensate for this.

If you want a small radio telescope I found this: http://www.haystack.mit.edu/edu/unde...srt/index.html, it gives details on how to build a radio telescope along with some projects for it and instruction Manuel and parts list is on the site. Would be interesting to build.
I can second this suggestion, if you happen to have a spare $6,000 burning a hole in your pocket. I've had the pleasure of playing with a couple of the 'old' SRT antennae; noise readings ~70 K, potential for 'aperture fever' satiety resolution as a VLBI, and - supposedly - relatively flexible electronics.
