A 119 GHz catr based on a 2.4m hologoram

摘要

A development work of a 2.4m x 2.0m hologram for testing the 1.1 m offset reflector of the Odin satellite at 199 GHz is reported. The analysis of the hologoram is based on physcial optics (PO) and finite difference time domain method (FDTD).The hologram is fabricated with an etching process. A comparision between the theoretical and measured quiet-zone fields of the hologram type of compact antenna test rnage (CATR) is made.
