IF signal conversion process

The following figure shows the process RVP10 follows to convert the IF signal into corrected reflectivity, velocity, and width, including:

  • IF signal processing
  • I/Q processing and clutter filtering
  • Range averaging and clutter microsuppression
  • Moment calculations (reflectivity, velocity, spectrum width)
  • Thresholding for data quality and speckle filtering
  • Reflectivity calibration
  • Algorithms for ambiguity resolution (dual PRF, dual PRT, random phase)
  • Calibration and testing
