As classical approaches with a reduced number of variables do not give satisfactory discrimination, we propose to use the envelopes of the received signals.We perform a k-means clustering and discuss the first results of this approach. %G English %2 https://cea.hal.science/cea-02434561/document %2 https://cea.hal.science/cea-02434561/file/201700000825.pdf %L cea-02434561 %U https://cea.hal.science/cea-02434561 %~ CEA %~ UNIV-TLSE3 %~ CNRS %~ UNIV-AMU %~ LMA_UPR7051 %~ EC-MARSEILLE %~ DEN %~ DEN-CAD %~ CEA-CAD %~ TEST-HALCNRS %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP
