Control about sea clutter level of marine RADAR

In this paper we reduce the sea clutter level of marine RADAR systems using improvement factors and velocity spreads. The sea clutter consists of sea state and wave height. The proposed method controls effectively the sea clutter in 1~7 levels. The sea and rain clutter velocity spreads also vary depending on the clutter size. The improvement factor of clutter is also predefined by calculating the clutter level. Pre-defined clutter level can be reduced sea and rain clutter from RF receivers.
