Abstract
In this work, a method for diagnostics of large reflector antennas for space applications is presented. By using a Calderón projection together with a Higher-Order (HO) Method of Moments (MoM) discretization, the inverse electromagnetic scattering problem is solved in an efficient manner, allowing for diagnostics based on the equivalent currents. This method is referred to as the Calderón method and is shown to be well suited for use in antenna diagnostics applications. Two reflector antenna cases have been analysed and significant reductions in computation time and memory allocation requirements are observed in comparison to other state-of-the-art solvers.
