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

Table 1

Feature vectors for targets 𝑗=𝑆0, 𝑗=𝑆1, and 𝑗=𝑆2 and Φ^𝑆𝑂1={10−30^∘,280−350^∘,5.3−9.65GHz}^𝑆𝑂1. Heights (z) are normalized with respect to the lowest value in order to match interferometric height conventions.
