Optimal Shape Design of a Cavity for Radar Cross Section Reduction
SIAM Journal on Control and Optimization, 2014This paper focuses on the reduction of radar cross section (RCS) for a cavity embedded in an infinite ground plane. By introducing a transparent boundary condition, the unbounded scattering problem is reduced to a bounded domain problem. RCS reduction for the cavity is formulated as a shape optimization problem involving the Helmholtz equation.

A Prismatic Conformal Metasurface for Radar Cross-Sectional Reduction
IEEE Antennas and Wireless Propagation Letters, 2020A prismatic conformal metasurface, based on optimized multielement phase cancellation, is proposed for wideband radar cross-sectional (RCS) reduction. The metasurface is composed of 35 lattices located in seven zones of a prismatic structure. The lattices in different zones are simulated under corresponding incident angles and taken into account the ...

Radar cross‐section reduction design for a microstrip antenna
Microwave and Optical Technology Letters, 2014ABSTRACTA microstrip antenna with reduced monostatic radar cross section (RCS) is presented. The RCS reduction is realized by replacing the solid ground plane of the reference antenna with a complex ground plane composed of bandstop frequency selective surface unit cells. In the mean time, the radiation performances are properly maintained.

Radar Cross Section Reduction of a Cavity in the Ground Plane
Communications in Computational Physics, 2014This paper investigates the reduction of backscatter radar cross section (RCS) for a rectangular cavity embedded in the ground plane. The bottom of the cavity is coated by a thin, multilayered radar absorbing material (RAM) with possibly different permittivities.

Broadband AMC Surface for Radar Cross Section Reduction
2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018A broadband artificial magnetic conductor (AMC) surface is designed for radar cross section (RCS) reduction in this paper. The proposed AMC configuration is composed of two different AMC unit cells, which contribute to destructive phase difference $(180^{\mathrm{o}}\pm 37^{\circ})$ over a broad frequency band. With fan-type arrangement of the two AMC

Broadband Coding Metasurface for Radar Cross Section Reduction
2018 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC), 2018In this paper, 1-bit coding metasurface is presented and used to reduce the radar cross section (RCS) of metallic object over a wide frequency range in microwave region. We propose and design a structure-simple unit cell to realize 180° (or π) phase difference, and 4×4 unit cells compose “0” or “1” elements which arrange into a 1-hit coding metasurface.

Radar cross section prediction and reduction for naval ships
Journal of Marine Science and Application, 2012Radar cross section (RCS) is the measurement of the reflective strength of a target. Reducing the RCS of a naval ship enables its late detection, which is useful for capitalizing on elements of surprise and initiative. Thus, the RCS of a naval ship has become a very important design factor for achieving surprise, initiative, and survivability ...
