An error controllable algorithm is proposed to efficiently evaluate two-dimensional (2-D) monostatic radar cross section (RCS) from electrically large and complex targets. The algorithm employs interpolative decomposition (ID) to conduct low-rank decomposition on the excitation matrix consisting of multiple right-hand-sides (RHS's) to figure out the so-called skeleton incidents. After the solutions...
In this paper, a high performance parallel multilevel fast multipole algorithm (MLFMA) is designed and developed to compute scattering from extremely large targets exceeding 1000 wavelengths by integrating various novel implementation tricks. This parallel MLFMA is presented in a multilevel style, where implementation tricks are discussed, compared, and developed in detail.
