KLT, A New Algorithm For SETI

Abstract

In 1960, the astronomer Frank Drake listened to the stars Tau Ceti and Epsilon Eridani, searching for extra terrestrial intelligent signals: the so called “Ozma project” was the first experimental SETI attempt. Since then, SETI has been mainly radio, although optical SETI and the technosignature search are becoming more and more of interest. Several methods exists in order to process radio signals and the KLT—Karhunen Loève Transform—is one of those. First in 1983 at the Nancy Radiotelescope, second at Ohio State University respectively Francois Biraud and Robert Dixon tried to use it recover very feeble signals buried into noise. In these proceedings, we analyze a new technique for KLT.
