Optimization Method of Array Pattern Synthesis

An optimization method of conformal array pattern synthesis based on the aperture field inversion is proposed in this paper. The planar near-field data is inverted to the aperture field plane and the low side-lobe pattern is obtained by compensating the amplitude and phase of elements. The optimization of conformal array is transformed into the optimization of planar array by means of the method which avoids the tedious solving progress caused by cross polarization and non-coplanar phase center. The method is used to synthesize the radiation performance of the conformal antenna with the shape of an aircraft fuselage. The results show that the method is feasible and greatly improves the optimization efficiency of conformal array pattern synthesis.
