The proposed development should lead to an antenna design tool where uncertainty quantification techniques are fully integrated andcan be invoked for all results of interest. In order to maximize the impact of the new approach, the techniques should be integrated into an existing state-of-the-art software for analysis of antenna systems, including relevant surrounding structures such as a spacecraft for on-board systems. The uncertainty quantification tool should be able to assess variations in the feed geometry (e.g. corrugated or spline horn), the antenna geometry (e.g. array of feeds, reflector configuration), the platform, or all the above at thesame time. It is anticipated that uncertainty quantification techniques may also necessitate an acceleration of some of the analysis algorithms used by the tool without compromising its numerical accuracy. The objective of this activity is to provide a more efficient uncertainty quantification tool for antenna systems, including also interactions with the surrounding structures (e.g. spacecraft). Mathematical methods enabling more efficient sensitivity analyses shall be investigated and compared. The most suitable sensitivity analysis procedure for typical antenna problems shall be implemented onto a state-of-the-art RF analysis tool, and its performance shall be demonstrated through specific test cases.NOTE: This activity is currently in the GSTP Work Plan but will only be implemented after confirmation of financial support from Delegations. The final list of participating states will be known at tender issue.
