Monostatic RCS Analysis of Electrically Large Structures using Integral Equations
The monostatic radar cross section (RCS) is an important design parameter for many applications but accurate RCS prediction of an electrically large structure continues to be a challenging task. High accuracy demands and a complicated geometry often mean that asymptotic methods are not applicable, while a full-wave method has traditionally required very large computational resources. In the present paper, we avoid the O(f6) computational time scaling of the Method of Moments by applying the Multi-Level Fast Multipole Method (MLFMM). A range of modifications to the traditional way of applying MLFMM to monostatic RCS are implemented in order to achieve strong computational performance even on modest hardware.
