Angular glint is a significant electromagnetic (EM) scattering signature of extended radar targets. Based on the adaptive cross approximation (ACA) algorithm accelerated method of moments (MoM) and the plane incident wave assumption, the narrowband, wideband and newly developed high-resolution range profile
(HRRP) based angular glint calculation formulations are derived and applied to arbitrarily shaped three-dimensional (3D) perfectly electrically conducting (PEC) objects. In addition, the near-field angular glint is emphasized, which is of great importance for radarseeker applications. Furthermore, with the HRRP based angular glint, an approach to rigorously determine range resolution cells which own relatively smaller angular glint is provided. Numerical results are presented with new findings to demonstrate the usefulness of the developed formulations.
