Radar Absorber Scattering Structure for Ghost Target Reduction

The radome employs variable thickness design where the thickness is optimized locally in different regions rather than being uniformly thick. The thickness distribution is tailored to achieve adequate protection and scattering reduction in critical areas while minimizing weight in less critical areas.

The radome utilizes composite material construction that combines different materials with complementary properties to achieve both protection and scattering reduction functions with optimized weight, avoiding the need for uniformly thick single-material construction.

The RF absorber is strategically placed only in specific regions where scattering problems occur most severely, rather than using uniform coverage. The absorber thickness and material properties are optimized locally to achieve maximum scattering reduction with minimum material quantity.

The patent optimizes the RF absorber material parameters including thickness, permittivity, and loss tangent to achieve effective scattering reduction. By carefully selecting and tuning these parameters, the absorber achieves maximum performance with reduced material quantity.

The radome and RF absorber are designed as separate, modular components that can be manufactured independently using standard processes. This segmentation allows each component to be optimized and manufactured separately, reducing overall manufacturing complexity while achieving the required scattering control when assembled.

The patent employs curved and rounded geometric features in the radome and absorber designs rather than sharp edges and complex angular structures. These curved geometries are easier to manufacture using conventional molding and fabrication processes while effectively controlling scattering patterns.
