Radar cross-section (RCS) analysis of high frequency surface wave radar targets [PDF]

open access: yesTurkish Journal of Electrical Engineering and Computer Sciences, 2010
Realistic high frequency surface wave radar (HFSWR) targets are investigated numerically in terms of electromagnetic wave – target interactions. Radar cross sections (RCS) of these targets are simulated via both the finite-difference time-domain (FDTD) method and the Method of Moments (MoM).

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).

Radar cross section (RCS) measurements [Testing ourselves]

open access: yesIEEE Antennas and Propagation Magazine, 2013
The radar cross section (RCS) is a critical parameter that describes the electromagnetic wave – target interaction. Its accurate prediction has long been a hot research and engineering topic. Today, RCS prediction of real targets is achieved via either numerical simulations or measurements. Here, indoor RCS measurements are reviewed in a tutorial.

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.

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 ...

Transparent metamaterial absorber with broadband radar cross‐section (RCS) reduction for solar arrays [PDF]

open access: yesIET Microwaves, Antennas & Propagation, 2020
Solar arrays are the primary energy source of the satellite. In this study, a metamaterial absorber for solar arrays with simultaneous high optical transparency and broadband microwave absorption is presented. By tailoring the reflection response of meta‐atoms, 87% absorption performance from 6.8 to 18 GHz is obtained.
