Zusammenfassung |
A model-based fuzzy classification method for C-band polarimetric radar data,
named Fuzzy Radar Algorithm for Hydrometeor Classification at C-band
(FRAHCC), is presented. Membership functions are designed for best fitting
simulation data at C-band, and they are derived for ten different hydrometeor
classes by means of a scattering model, based on T-Matrix numerical method.
The fuzzy logic classification technique uses a reduced set of polarimetric
observables, i.e. copolar reflectivity and differential reflectivity, and it
is finally applied to data coming from radar sites located in Gattatico and
S. Pietro Capofiume in North Italy. The final purpose is to show qualitative
accuracy improvements with respect to the use of a set of ten bidimensional
MBFs, previously adopted and well suited to S-band data but not to C-band
data. |
