I am studying how to indentify and remove RFI in astromony singal,I want to konw how to get real RFI data and processs on them?Thinks!!!
Hello,Can we communicate by email?
Hi there,
My apologies, somehow this slipped through the cracks. Did you find a data set to work on?
If not, most radio telescopes on Earth have public data archives where all data is free to download after a year or two. Here are two archive examples:
(Pretty much all data in my experience has a few percent RFI from these sites. Finding a high RFI one would probably just be word of mouth as that's not a recorded statistic, I don't have one saved right now or anything.)
You can then do a google search to find tutorials on how to process the data. Here's some the VLA has for example, with data sets you can download- https://casaguides.nrao.edu/index.php/Karl_G._Jansky_VLA_Tutorials
It looks like out of those this one has RFI in the data set and points out how to get rid of it, so it might be a good one to start with- https://casaguides.nrao.edu/index.php?title=VLA_Radio_galaxy_3C_129:_P-band_continuum_tutorial-CASA5.5.0
Finally, most astronomers won't do RFI manually in the long run, but use a flagging software. I use this one for most of my data- https://sourceforge.net/p/aoflagger/wiki/Home/
I hope this helps! Sorry again for the delay.
