AbstractThe Fast Illinois Solver Code (FISC) requirements about memory and central processing unit (CPU) time are discussed. FISC is designed to compute the RCS of a target described by a triangular facet file. Both complexities for the CPU time per iteration and memory requirements are of O(N log N), where N is the number of unknowns. The N scales approximately as the surface area of the scatterer, or N≈350 S (0.1λ/a)2. The memory requirement is approximately 0.75 S[0.2+0.8(0.1λ/a)2] MB. If one CPU of SGI CRAY Origin2000 is used, for each frequency, FISC needs the set-up time Tfill≈5 sec., and solution time Tsolve = 0.1 Slog(S)(S1/4+IopenS1/2) sec for each angle.
