Optimum Synthesis of Pencil Beams with Constrained Dynamic Range Ratio

Table 3

Properties of proposed pencil beam array with 30 elements and beamwidth of 6°, compared with array having equiripple sidelobes and unconstrained DRR [24], and with array having minimum DRR for given SLL and all positive coefficients [7]. Improvement is highlighted in bold.
