This paper describes how the bistatic radar cross section (RCS) experimental setup of the “Centre Commun de Ressources en Microondes” (CCRM) was used to precisely determine various scattering quantities and how we took profit of the large scattering angular range available with this setup. Results on extinction cross section, linear degree of polarization and other scattering quantities of interest are presented. We also show how those results are interesting in different domains where scattering phenomena are studied thanks to the scale invariance properties of the Maxwell equations using the so called microwave analogy.
