Full-Wave Monostatic Radar Cross Section using the Multilevel Fast Multipole Method

29 Mar 2023

An efficient full-wave solver for the computation of monostatic Radar Cross Section (RCS) for electrically large structures using the method of moments is developed. This is accomplished by utilizing higher-order basis functions, to reduce the number of unknowns, and the multilevel fast multipole method, to reduce the computational effort and memory footprint. These techniques are combined with a compression of the right hand sides arising from the different incident angles. We demonstrate that this solver allows for efficient full wave RCS computations of electrically large structures on a laptop.
