Radar cross-section enhancement techniques
2017 IEEE International Conference on Computational Electromagnetics (ICCEM), 2017The quasi-superdirective reradiation and in-phase retroreflection are presented for the sake of monostatic radar cross-section enhancement. Two passive structures, including a post-loaded thin plate and a metasurface-coated cylinder, are proposed to demonstrate the validity of the concepts.

Radar cross section (RCS) is a measure of the electromagnetic energy intercepted and reradiated at the same wavelength by any object. The dimensions are those of an area, usually square meters. The object of interest is compared to an idealized object that is large with respect to a wavelength, has an intercept area of one square unit, is perfectly ...

Radar Cross Section Enhancing Structures for Automotive Radars
IEEE Antennas and Wireless Propagation Letters, 2018As automotive radar and driver assistance systems prevail, weak scattering targets such as pedestrians and bicycles can be applied with radar cross section (RCS) enhancing structures to improve road safety. Low-profile structures, which comprise straight and ring-shaped ridges mounted on metal plates, are developed in the 24 GHz band to provide the ...

Optimal radar cross section estimation in synthetic aperture radar
2017 IEEE First Ukraine Conference on Electrical and Computer Engineering (UKRCON), 2017Synthetic aperture radar (SAR) is a widely used technique suited for real-time and all-weather imaging of natural surfaces and artificial objects. To improve image resolution and increase accuracy of radar cross section estimation the problem of statistical synthesis of signal processing algorithm in SAR is solved. Proposed method allows to form images

Radar-Absorbent Material and Radar Cross Section
2020Radiation-absorbent material, usually known as RAM, is a material which has been specially designed and shaped to absorb incident RF radiation, as effectively as possible, from as many incident directions as possible. The more effective the RAM, the lower the resulting level of reflected radio-frequency (RF) radiation.

Compressive Radar Cross Section Computation
2020Compressive Sensing (CS) is a novel signal-processing paradigm that allows sampling of sparse or compressible signals at lower than Nyquist rate. The past decade has seen substantial research on imaging applications using compressive sensing. In this thesis, CS is combined with the commercial electromagnetic (EM) simulation software newFASANT to ...

Radar cross-section measurements of insects
Proceedings of the IEEE, 1973A simple method to measure backscatter cross sections of live insects at 10-cm wavelength using an ultra-high resolution scanning FM-CW tropospheric radar sounder is described. The technique involves suspending an insect along a line between two metal spheres and comparing insect and sphere cross sections.
