abstract: It is well known that manufacturing errors, mutual coupling effects, mechanical deformations, and climatic changes can cause deviations (both in phase and amplitude) of the excitations in planar phased arrays from their nominal values. As a main consequence, the radiated pattern can differ from the expected one, and the overall system performances can be lower than expected. In this work, an innovative sensitivity tool has been developed to analyze the impact of uncertain but bounded excitation tolerances in planar phased arrays on the radiated pattern. More in detail, the proposed methodology exploits the rules of interval analysis (IA) and the Minkowski sum in order to estimate narrower but inclusive bounds than standard Cartesian-based IA approaches. Some numerical results are shown, in order to verify the effectiveness of the developed sensitivity tool and to study the influence of excitation tolerances in generating a beam pattern with a given sidelobe level (SLL).
