Abstract

In this investigation, the monostatic inverse synthetic aperture radar (ISAR) characteristics of electrically large zigzag-grooved structures were numerically analyzed for the far-field at X-band frequencies. The zigzag-grooved structures were all assumed to have perfect electric conductor (PEC) properties. Their ISAR data were post-processed from their monostatic radar cross section (RCS) data generated from physical optics and ray-tracing numerical computations. Scattering centers from the ISAR data were characterized using hot-spot analysis diagrams, devised solely for this purpose.
