This work focuses on optimal synthesis of a linear array to achieve narrower half-power beam width, reduced side-lobe levels, and nulls control as per the need of the design. To accomplish these goals we considered the optimization of excitation amplitude, phase and inter-element spacing of the array. Since, the optimization problem involved is not convex(More)
