Fast MBF based method for large random array characterization

The method proposed by the authors to reduce the computational cost devoted to solve the full EM problem in such arrays is based in the macro basis function technique and the interpolation method. On the other hand, it is shown how the embedded element pattern convergence within a radius of influence allows us to account only for a few tens of significative elements when computing the aforementioned pattern for each antenna. This approximation provides a further computational cost reduction and is a first step towards a very fast full-wave simulation tool for very large random arrays.Anglai
