 Cassbeam is a Cassegrain antenna ray tracer.  A Cassegrain antenna  is a double reflector system which works on the principle of cassegrain  optical telescope.  A high gain cassegrain reflector antenna in Ku-band  has been successfully developed for command transmit application for the  missile programme. It can also be used for monopulse radar, satellite  communication.  .  Based on an input text file, it computes several properties of the  antenna including gain, zenith system temperature, and the beam, in full  polarization.  All calculations are done in the transmit sense  and use reciprocity to relate to the equivalent receiving system.  .  Additionally, cassbeam allows deformations, or pathologies of the  optics to be modelled.  Currently this is limited to rotations and  translations of the feed and secondary.  In the future, large scale  deviations in the primary (such as a misplaced panel) will likely be  supported. |
