About
With the Uncertainty Quantification (UQ) product, the antenna designer may augment the usual antenna design process with uncertainties on design parameters and get data on the expected antenna performance and confidence intervals. Using advanced statistical methods, UQ works together with TICRA Tools antenna analysis products, where uncertainty due to any variable specifying the antenna may be included — geometrical dimensions, element positions, surface distortions, material parameters, array excitation coefficients, and more. The outcome is expected performance and confidence intervals (e.g. for radiation pattern) as well as probability distributions for key parameters such as peak directivity. Sobol indices identify which design variables contribute most to total uncertainty. UQ is integrated in the TICRA Tools framework, working with GRASP, ESTEAM, CHAMP 3D, QUPES, and/or POS, and employs a higher-order approach that provides accurate uncertainty estimates in reasonable time, avoiding overdesign.
