Abstract:

Difficulties associated with extremely large targets, including construction of the geometry tree in the algorithm, reduction of the number of far-field patterns and fast computation of radar cross section, are pointed out. Based on the architecture of popular parallel platforms, distributed memory parallel systems, and properties of targets with extremely large sizes, relative solutions are proposed. The efficiency of the proposed parallel multilevel fast multipole algorithm (MLFMA) scheme is validated by successful computations of scattering from targets with over five hundred million unknowns and several thousand wavelengths in size.
