A probability based sea clutter suppression method for polarimetric weather radar systems

Beyond calibration the mitigation and suppression of clutter signals is still a challenge in radar remote sensing. The weather radar market trend (for aviation and hydrological/meteorological applications)shows explicitly that the decision for polarimetric radar systems is continuously increasing, since the potential capabilities and benefits of dual polarization radar systems are well known. This publication presents an automatic discrimination method between weather and sea clutter based on multi parameter polar data sets (Doppler and polarimetric) as well as the generation of a sea clutter probability index. Additionally a new polar based clutter type map will be introduced and the suppression of sea clutter signals outlined.
