Abstract :
Based on adaptive cross approximation (ACA) algorithm accelerated method of moments (MoM) using RWG basis functions and with plane incident wave assumption, both far-field and near-field angular glint calculation formulations are derived and applied to perfectly electrically conducting (PEC) objects, which are of great importance for radar seeker applications. Numerical results are presented with new findings to demonstrate the usefulness of the developed formulations.
