Terahertz radar cross section measurements [PDF]

open access: yes35th International Conference on Infrared, Millimeter, and Terahertz Waves, 2010
We perform angle- and frequency-resolved radar cross section (RCS) measurements on objects at terahertz frequencies. Our RCS measurements are performed on a scale model aircraft of size 5-10 cm in polar and azimuthal configurations, and correspond closely to RCS measurements with conventional radar on full-size objects.

Wind Turbine Radar Cross Section [PDF]

open access: yesInternational Journal of Antennas and Propagation, 2012
The radar cross section (RCS) of a wind turbine is a figure of merit for assessing its effect on the performance of electronic systems. In this paper, the fundamental equations for estimating the wind turbine clutter signal in radar and communication ...

A Single-Antenna Method and Post-Processing Strategy for Radar Cross-Section Measurements at Near-Field Ranges [PDF]

open access: yesSensors, 2022
The single-antenna technique proposed in this paper was developed for measuring the radar cross-section at near-field distances in a real environment, from reflection coefficient measurements on the antenna.

Analysis of Quantum Radar Cross-Section by Canonical Quantization Method (Full Quantum Theory)

open access: yesIEEE Access, 2020
This article investigates the difference between two quantum-based theories to calculate the radar cross-section (RCS). Quantum radar cross-section (QRCS) has been commonly analyzed using the dipole approximation method, and the related results show that

Wideband RCS reduction due to plasma generated by radioactive nuclei for cylindrical object

open access: yesScientific Reports, 2022
Radar cross section reduction has been one of the most important research topics in recent years. Plasma-based stealth is a method of reducing the radar cross section, which dampens the electromagnetic waves and reduces the amount of return waves.

Reducing radar cross section by investigation electromagnetic materials

open access: yesAdvanced Electromagnetics, 2012
Decreasing the Radar Cross Section (RCS) is investigated in electromagnetic materials, i.e. double-positive (DPS) , double-negative (DNG) , epsilon-negative (ENG) and mu-negative (MNG) materials.
