Recent Developments in Large-Scale Array Analysis for Radio Astronomy Applications
This paper presents an efficient local solution-based solver with nested cross approximation (NCA) matrix compression for the analysis of large disjoint antenna arrays. Preliminary results demonstrate runtime improvements of about an order of magnitude over the multilevel fast multipole method (MLFMM) in the commercial FEKO software suite, for the computation of embedded element patterns (EEPs) in a large antenna array above an infinite perfect electrical conductor (PEC) ground plane. The solver is ideally suited to parallelisation.
