Scattering-Based Model of the SAR Signatures of Complex Targets for Classification Applications

Figure 3

Scattering maps obtained for the SPA (a), ICE (b), and FER (c) vessels at L, C, and X bands with 𝛽∈{295,315,335}^∘ and 𝜙=20^∘. They have been analyzed with the Pauli CTD theorem for a dynamic range of 25 dB. The lengths of the SPA, ICE, and FER ships are 30, 70, and 200 meters. Circles isolate the PePSs used in the feature vectors of Table 1.
