A Gregorian Dual Reflector configuration is proposed to scan an area ranging from -1.2° to 1.2°. The proposed configuration consists of a paraboloidal main reflector, elliptical sub-reflector operating at Ku-Band and sharing common feed point. Imaging arrangement is obtained by translation, rotation and focal length adjustment of the feed. An attractive feature of the imaging arrangement is that they are capable to scan one beam electronically and generate multi beam coverage in a limited field of view. As an application, a 0.6m diameter main reflector with a cluster of WR-51 waveguides is utilized to get an H.P.B.W of 1.8°.
