Summary:
The Compressed Sensing (CS) technique is applied to the finite element method (FEM) for fast radar cross section (RCS) calculation over a wide incident angular band. Rather than point-by-point solving multiple right-hand vectors of each incident angle, the right-hand sides are first compressed and then recovered to find each incident angle response in CS procedure. The numerical example shows the proposed approach leads a magnitude decrease of computation time without losing accuracy.
