Near field to equivalent currents transformation with radome applications

In English Knowledge about the equivalent currents distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to the equivalent currents distribution is analyzed. The transformation is based on a singular value decomposition of the surface integral equation that relates the equivalent currents to the near-field data. The mathematical model can easily be used for arbitrary geometric structures. The symmetries of a specific problem are utilized to reduce the computational complexity. Both synthetic data and measured data are used to verify the algorithm
