Optimum Synthesis of Pencil Beams with Constrained Dynamic Range Ratio

Table 2

Properties of proposed pencil beam array with 16 elements and beamwidth of 10°, 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.
