بررسی میزان کاهش سطح مقطع راداری صفحه‌های آلومینیومی تخت و تک انحنایی در بازه‌ی فرکانسی باند ایکس

This research focuses on analyzing and investigating the reduction of the radar cross-sectional area (RCS) of a flat aluminum plate and a single-curved aluminum plate using cross-sectional shaping methods in the X-band frequency range. First, the equations governing the RCS of these two geometries are analyzed using geometrical optics, the method of moments, and a review of Maxwell's equations within electromagnetic wave theory. A plate thickness of 5 mm, similar to that of an aerial structure, is modeled using Comsol software. After simulating the incidence of microwave waves on the surface of the structure in the X-band, polar diagrams of the reflection patterns and scattering parameters are evaluated. Finally, a comparison between the two geometries is conducted to determine the optimal shape for RCS reduction. The results indicate that the single-curved plate demonstrates superior performance in reducing electromagnetic wave reflection, achieving an RCS reduction of up to 11 dB at a frequency of 10 GHz compared to the flat plate.
