2.1.8 Adjusting spectral width thresholds
The thresholding of spectral width data is the same as for radial velocity. See description above.
2.2 Reflectivity and Doppler speckle remover
Speckle removers can be applied to all final physical moments (Z, UZ, V, W). They can be switched on or
off separately for reflectivity and Doppler results. Speckle removers identify isolated valid bins in the
output data ray. In that case, they are removed and flagged as unvalid ( or thresholded).
The speckle remover removes isolated valid data range bins, whose neighbors have been thresholded
before (NOISE threshold, CCOR threshold...). The reflectivity speckle remover can be applied to
corrected and uncorrected reflectivity data (Z and UZ). The Doppler speckle remover can be applied to
radial velocity (V) and spectral width data (W).
