Abstract :
This paper presents the results of an investigation of the vertical plane beam scanning of an offset reflector antenna by lateral displacements of the multimode feed horns array, which was earlier shown to have multiple phase centres in the horizontal plane. The antenna was found to have both multiple phase centres, as well as, the beam scan. It is suitable for the space borne radar application at X-band frequency
