Error Recognition In Interferometric Imaging Analysis
 
  1 Goals:  
 
 

  • Locate the causes of possible errors and defects

  • Relate visibility errors to image defects

  • Learn methods of diagnosing common problems

  • Find solutions for correction of errors

  
 
  2 Where Are Errors Introduced in the "Signal" Path?  
 
 

  • Far Field (atmosphere,ionosphere,beyond)

  • Near Field (atmosphere,ionosphere)

  • Antenna Frontend (antenna,optics,horn)

  • Antenna Backend (amplifiers,digitizers)

  • Baseline (correlator)

  • Post-Correlation
