Adaptive Clustering-Based Marine Radar Sea Clutter Normalization

Figure 1

Amplitudes of the marine radar echoes with and without targets. (a₁), (a₂), (a₃), and (a₄) are sea clutter amplitude data without targets recorded in four different sea states (L₁, L₂, L₃, L₄), respectively, and the corresponding sea states satisfy . (b₁), (b₂), (b₃), and (b₄) are amplitudes of the radar data with different targets in the four sea states as well. red curves indicate the likely targets.
