| Abstract: |
| The paper presents the method for calculating the compound feed phase center of shaping subreflector of dual-reflector antenna based on GOT.Using dyadic reflection coefficients,the scattering field including difference beam of subreflector and the aperture distribution in antenna are obtained.So the calculation of perfornlance parameters of shaped subreflector antenna has been solved. |
