At high grazing angles, the sea clutter background has a strong impact on 3-D imaging. A method for Radon transform based sea clutter suppression is given in this paper. ISAR technique is used to get two-dimension image of the target firstly. Then angular motion compensation and Radon transformation are performed to the ISAR image. A novel search algorithm based on the edge detection is used to divide the target from the sea clutter in the end. The result of the 3-D imaging shows the effectiveness of the new method for sea clutter suppression.
