Least squares pattern synthesis for conformal arrays

The problem of synthesising low sidelobe beams from conformal arrays consis ting of few elements and large radius of curvature is addressed. Experiment al resufts are presented for a 12 element array of linearly polarised eleme nts forming a faceted array with radius of curvature 1.5m. It is shown that by calculation of an aperture correcting matrix sidelobe levels of 40dB ca n be obtained from the array by application of conventional linear array Ta ylor weights. Beam steering is achieved by aperture phase tapering while lo w sidelobe levels are maintained.
