Abstract :
The investigation results of multimode feed horns are presented, which provide multi-phase centre radiation performance with the reflector. These feed horns with reflector assembly are suitable for radar systems, where ground moving target indicator (GMTI) mode implementation is desired. The simulations were carried out using Ansoft Corporation´s HFSS v8.5 for feed horn, and Ticra´s GRASP v7.0 for the reflector.
