First light on additive interferometer
Admin
Experiencing difficulties with my multiplying interferometer (which means it doesn’t work yet!), I am trying a simpler additive interferometer using 2 x Nooelec 1.4GHz dishes, SAWBird+ H1M LNAs at dishes,…
Determining the galactic rotation curve of the Milky successfully with my 1420MHz array
Galactic rotation curve from my data: Below shows exercise of picking points for curve above in my data: Compare my rotation curve above with typical Keplarian rotation curve (not from…
Interferometer test rig
My proposed test rig for interferometer, although I intend to change the splitter to power splitter. Andy
The 2 aerials of LIMA (Lichfield Interferometer Mini Array) 30/11/23
I still don’t think my interferometer is going to work! But here the 2 x Nooelec 1420MHz mesh antennae that will be used. Andy
Getting closer to the horizon on 1420MHz array…..
I have added some extension arms to the elevation mechanism on my homemade wooden mount for my 1420MHz hydrogen array to get closer to horizon as in this photo and…
The hydrogen map develops!
The arms of the Milky Way are beginning to emerge in my 1420Mhz radio telescope using ezRA software and 86 x 86cm ex-military array. I would particularly direct readers to…
“First Light” of AD8302 Interferometer Board….without aerials!!
I decided to see what output came out of the AD8302 phase comparator on my interferometer board – no aerials. Is anyone able to explain to me what I seeing…
