"The purpose of this work is to explain and calculate these various effects with regard to antenna efficiency and to outline the design principles for the support of this experimental primary feed. The analysis and computation of the blockage has been extended for two cases of dual reflector systems (classical/shaped subreflector). The complete computer programs are made to handle the three different cases mentioned above with minimum effort. Test cases are listed toward the end of the report to help the designer operate the program and seek the desired output information"--Summary. Artificial satellites in telecommunication.
