SUMMARY

Arrays, such as the Expanded Very Large Array (EVLA), convert light from astronomical sources into data through the application of Fourier Transforms. This mathematical technique is essential for analyzing the frequency components of the light signals. After transformation, deconvolution is necessary to eliminate side lobes that can distort the data interpretation. Understanding these processes is crucial for anyone involved in radio astronomy or signal processing.

PREREQUISITES
  • Basic knowledge of interferometry
  • Understanding of Fourier Transforms
  • Familiarity with deconvolution techniques
  • Concepts of signal processing
NEXT STEPS

Hi all,

I've been reading on how arrays (eg. EVLA) turn light from space into data, but I don't really get it. I know it has a lot to do with Fourier Transforms, but I can't find anything that gives a good and simple outline as to why they're used. And then once it's been transformed it needs to be deconvolved to get rid of the side lobes, but the order and reasons are a bit muddled in my head.

Can anyone elxplain it? I don't mind a bit of math but I'm looking for a general outline before I get bogged down in the numbers.

Thanks
