A Fast Algorithm for Monostatic RCS Based on Lu Decomposition

Abstract:

Compared with bistatic RCS, the monostatic RCS calculation is more difficult for the needs of surface current on scatterer induced by the incident wave of every single angle, so the calculation burthen is very large. Based on the character of impedance matrix of MOM is invariable whether the angle of incident wave was changed, this paper proposes a fast algorithm for monostatic RCS based on LU decomposition. Numerical results show out that this algorithm can compress the computation burthen of monostatic RCS significantly, and this algorithm is easy to operate.
