Abstract

Computer-generated holograms can be applied in space terahertz technology; they are particularly suitable as focusing elements in compact test ranges, for example, in testing of high-gain antennas and measuring radar cross section (RCS) of scaled models. Radio holograms have also been demonstrated in other millimeter- and submillimeter-wave beam-shaping applications, such as the creation of non-diffracting mm-wave Bessel beams, mm-wave vortices, and custom-designed beam patterns. During summer 2003 we built a temporary measuring facility at the High Voltage Institute of the Helsinki University of Technology to test the ADMIRALS antenna built by EADS Astrium. The measurement results obtained at 322 GHz are so promising that we are currently proposing a hologram CATR test for the Planck telescope at 500 GHz.
