RCS of printed dipole antenna arrays with a dielectric cover

Summary form only given. A full-wave solution for the RCS (radar cross section) of a finite array of printed dipoles in a substrate-superstrate geometry is discussed, as well as a massively parallel computer implementation of the solution. RCS data were obtained as a function of the printed dipole antenna array geometry and incident signal properties. The approach is to solve the exact electric field integral equation utilizing the spectral-domain moment method. The use of massively parallel computing overcomes the computational intractability of the full-wave moment-method solution. The moment-method solution obtained is based on massively parallel computers with hypercube architectures. The moment-method solution utilizes toroidal wrap mapping to minimize the communication penalty associated with a large number of processors. This scheme achieved order-of-magnitude speedups relative to a Cray X-MP supercomputer.<>
