Beampattern Synthesis With Dynamic Range Ratio Constraint via Sequential Convex Optimization

In this paper, we consider beampattern synthesis with a constraint on the dynamic range ratio (DRR), which is defined as the proportion between the maximum and minimum amplitude excitations applied to the array elements. Utilizing the trigonometric function technique, we reformulate and simplify the non-convex constraint on DRR. This allows us to derive a new beampattern synthesis formulation with DRR constraint, which can be solved through sequential convex optimization. Compared to existing algorithms, the proposed algorithm can be executed very easily. Moreover, our algorithm exhibits high effectiveness on both focused and shaped beampatterns. Both theoretical and simulation results confirm that the proposed algorithm does not rely on the initial setting and exhibits good convergence performance. Representative simulations are provided to demonstrate the effectiveness and superiority of the proposed algorithm in various scenarios.
