Abstract :
Diffraction effects of the edge region within the antenna array aperture have been discussed with the numerical simulation and measurement in the antenna array monostatic Radar Cross Section (RCS) analysis. Research illustrates that the edge of array presents dominant diffraction effects on the antenna mode RCS character evaluation in a wide frequency range, and bistatic RCS character proposes Radar Absorbing Material (RAM) is an effective approach for the shielding the edge diffraction.
