摘要：
We study pattern optimization of a parabolic reflector with planar-array feeds and cluster feeds. The optimization is carried out within conjugate gradient method (CGM) in which optimum weight vector of linearly constrained minimum variance (LCMV) beam former is used as the initial condition, The optimization with CGM to determine element weights is found to yield better sidelobe suppression and true settlement of desired scan direction compared to the LCMV beam former and conjugate field matching (CFM) techniques for a continuous beam-scanning case, The proposed method is also applied to the multibeam reflector-antenna design.
