A new method to fit real sea clutter data based on IPIX radar

Real clutter data fitting is very important for reach on clutter characteristic. In this paper, we proposed a new method to fit real clutter data of IPIX ice radar. Different distributions are used to fit different regions. KA distribution is adopt to fit the tail data part while K distribution is adopt to fit other part. Meanwhile, coordinate change is adopted to calculate tail data. Simulation shows that the method proposed in this paper can fit real clutter data of IPIX ice radar well not only on main part but also in the tail.
