Monopole Antenna Radar Cross Section Reduction with Plasma Helix

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

Wireless sensing and identification based on radar cross section variability measurement of passive electromagnetic sensors

In this paper, we present the wirelessmeasurement of various physical quantities from the analysis of the radar cross section variability of passive electromagnetic sensors. The technique uses a millimeter frequency-modulated continuous-wave radar for both remote sensing and wireless identification of sensors. Long reading ranges (up to some decameters) are reached at the expense of poor measur...

Radar Cross-Section Estimation of SAR Images

We present an algorithm that is able to smooth out the speckle from many SAR images and which does not suuer from the drawbacks of multilooking. The algorithm is able to preserve the detail and resolution of the original image while producing a smooth, real-valued output. In many cases the quality of the smoothed image is suuciently high that it may be used with standard optical post-processing...

Radar Cross Section Measurements of Frequency Selective Terahertz Retroreflectors

The radar cross section of spherical retroreflectors operating at terahertz frequencies is investigated. Several spherical retroreflectors with diameters ranging from 2 mm to 8 mm were fabricated and their radar cross section was measured at 100 GHz, 160 GHz, and 350 GHz. A frequency selective surface was applied to the retroreflectors to demonstrate proof of concept of narrow-band terahertz re...

Multiscale composite models based on the Bragg theOly are widely used to study the U1LlI<,,'l~"~' radar cross-section (NRCS) over the sea sllrface. However, these models are able to correctly reproduce the NRCS in ail configurations and wind wave conditions. have developed a physical model that takes into account, not only the Bragg nisl11, but also the non-Bragg scattering l11echanisl11 associ...
