Abstract :
Techniques are presented for improving the computational performance of radar cross section (RCS) prediction for aircraft. The motivation is to bring RCS and other electromagnetic requirements into a multidisciplinary, integrated design environment where optimization is likely to be employed. Techniques directly applicable to the method of moments and high frequency approximations are discussed
