| Abstract: | In S band operation, radar is typically interfered by the heavy weather clutter, especially in littoral regions where exists a specific mesocyclone. This paper introduces an approach to restrain the weather clutter residue after MTD processing that is the residual clutter pattern and adaptive threshold adjustment technology. Through employing the residual clutter pattern technology, we can automatically select out the optimal MTI filter in the clutter element according to the clutter residual corresponding with several different notch MTI filters, and enhance the improvement factor of system. |
