Fractal Metamaterial Absorber with Three-Order Oblique Cross Dipole Slot Structure and its Application for In-band RCS Reduction of Array Antennas [PDF]

open access: yes, 2014
To miniaturize the perfect metamaterial absorber, a fractal three-order oblique cross dipole slot structure is proposed and investigated in this paper. The fractal perfect metamaterial absorber (FPMA) consists of two metallic layers separated by a lossy ...

RCS analysis on different targets and bistatic angles using LTE frequency [PDF]

open access: yes, 2015
Moving target detection and location are a function of dependent bistatic Radar Cross Section (RCS) and radar design parameters which in our experimental study used long-term evolution (LTE) signal as a source for passive bistatic radar (PBR).

Classification of Radar Targets with Micro-Motion Based on RCS Sequences Encoding and Convolutional Neural Network

open access: yesRemote Sensing, 2022
Radar cross section (RCS) sequences, an easy-to-obtain target feature with small data volume, play a significant role in radar target classification. However, radar target classification based on RCS sequences has the shortcomings of limited information ...

Design and Implementation of Radar Cross-Section Models on a Virtex-6 FPGA

open access: yesJournal of Engineering, 2014
The simulation of radar cross-section (RCS) models in FPGA is illustrated. The models adopted are the Swerling ones. Radar cross-section (RCS) which is also termed as echo area gives the amount of scattered power from a target towards the radar.

A smart radar absorber based on the phase-switched screen [PDF]

open access: yes, 2005
Although conventional (i.e., passive) radar absorbers are widely used for modifying the radar cross-section (RCS) of current military platforms, such absorbers may not have adequate performance to satisfy future requirements.

Broadband radar cross section reduction by in-plane integration of scattering metasurfaces and magnetic absorbing materials

open access: yesResults in Physics, 2019
An in-plane hybrid design is proposed to achieve broadband radar cross section (RCS) reduction based on the integration of a diffusion scattering electromagnetic band-gap (EBG) metasurface and a magnetic absorbing material (MAM) at a thin thickness (d ...
