Abstract:

The shore-based radar plays an important role in clutter measurement and costal defense early warning. The inaccuracy of the sea-land clutter segmentation method based on typical geographic features is analyzed by S-band shore-based coherent radar clutter. To solve the problem that the offshore radar echo is impacted by land clutter, a sea-land clutter segmentation method based on phase information is proposed. The analysis of clutter amplitude distribution of several range cells in littoral environment shows that obvious differences exist in amplitude characteristics of the segmented sea and land clutter, which is a proof of the accuracy of the sea-land clutter segmentation. This method could render important reference for the processing of shore-based radar clutter.
