Radar cross section (RCS) of metamaterial absorbers
2016 10th European Conference on Antennas and Propagation (EuCAP), 2016In this paper, the design and simulation behaviour of the radar cross section of rectangular shape metamaterial in four models (Single element, stacked array along with the width, stacked array along with the depth, and stacked array along the combined width and depth axes) has been investigated and compared with each other. The single element has a FR-

Analytical Estimation of Radiation Mode Radar Cross Section (RCS) of Phased Arrays
IEEE Transactions on Vehicular Technology, 2020A novel analytical method has been proposed to compute radiation mode RCS of phased arrays. The array RCS is computed by tracing the path of an impinging EM signal as it travels through the array system. The scattered field contribution from each component of array and its feed network is expressed in terms of the reflection and transmission ...

The calculation of radar cross‐section (RCS) using the TLM method
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1989AbstractThe calculation of the radar cross‐section (RCS) of complex bodies using the symmetrical condensed TLM method is presented. The technique is based on a near‐to‐far field transformation of the TLM calculated near fields. Several two‐dimensional examples are presented which validate the method.

CFD spinoff - Computational electromagnetics for radar cross section(RCS) studies
Flight Simulation Technologies Conference and Exhibit, 1990A finite-volume discretization procedure derived from proven CFD methods is used to solve the conservation form of the time-domain Maxwell's equations, in order to compute EM scattering from layered objects. This time-domain approach handles both single-frequency/continuous wave and broadband-frequency/pulse incident excitation.

Radar cross section (RCS) statistical characterization using weibull distribution
Microwave and Optical Technology Letters, 2013AbstractRadar target's backscatter varies rapidly because of change in the relative position of each scatterer, body vibration while moving and so on. Weibull distribution is adopted as an inclusive description of the envelope of various targets' backscattering in this paper.

Bi-Static Radar Cross Section (RCS) Reduction of Impedance Cylinder
2006 IEEE Conference on Radar, 2006Reduction of RCS of military targets is important issue and can be regarded as part of passive ECM (electronic counter measure). Reduction of RCS is basically made by multilayer coating the surface of the target by lossy dielectrics. In this case, boundary condition which is satisfied on the surface of target can be modelled by IBC (impedance boundary ...

Journal of Optics, 2023
Abstract Integrated meta-devices are the need of modern stealth application systems and have recently received a great deal of attention. Most studies have concentrated on the physics and structural design of planar metasurfaces, while conformal design that is suitable for arbitrarily curved surfaces has been rarely discussed.

Theoretical Background for the Computation of Radar Cross-Section (RCS) Using NEC
2020The entire theoretical framework of NEC starting from the definition of integral equations to the solution of matrix equation is briefly introduced in this chapter. The basis functions used for representing the unknown current densities and the weight functions used for testing are also described in detail.

On the radar cross section (RCS) prediction of vehicles moving on the ground
AIP Conference Proceedings, 2014As readers should be aware, Radar Cross Section depends on the factors such as: Wave frequency and polarization, Target dimension, angle of ray incidence, Target’s material and covering, Type of radar system as monostatic or bistatic, space in which contains target and propagating waves, and etc.
