Ocean Clutter Characterization Based on PolSAR Data and Second-Order Statistics of Elementary Scatterers

open access: yesRemote Sensing, 2023
New features are proposed for sea clutter characterization when PolSAR data are employed. Cameron coherent target decomposition is applied to characterize each SAR pixel by means of the 8 basic elementary scatterers obtained by this decomposition.

Some relational structures with polynomial growth and their associated algebras II: Finite generation [PDF]

open access: yes, 2018
The profile of a relational structure $R$ is the function $\varphi_R$ which counts for every integer $n$ the number, possibly infinite, $\varphi_R(n)$ of substructures of $R$ induced on the $n$-element subsets, isomorphic substructures being identified ...
