The Efficacy of Radar Absorption Material on the Radar Cross Section Reduction of Simple Shapes
2021 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2021Radar Absorption Material (RAM) can absorb microwave, therefore is useful in assuring Electromagnetic Compatibility (EMC) for consumer electronics or achieving RF stealth for military platform. The specification of RAM is usually described in return loss per unit distance; however, the Radar Cross Section (RCS) is a more complicated function of ...

Coding Metasurface for Radar Cross Section Reduction
2020 IEEE 3rd International Conference of Safe Production and Informatization (IICSPI), 2020In recent years, the concept of metasurface has been proposed and developed, researchers has also put forward its some applications, such as introducing an abrupt phase shift, polarization conversion and holography et al. Additionally, metasurface is used to realize the RCS reduction.

Radar Cross Section Reduction Based on Metasurface
2018A novel polarization insensitive metasurface for backscattering Radar Cross Section (RCS) reduction is designed and studied. The proposed metasurface consist of carefully arranged unit cells, which enables estimated uniform diffusion of incoming electromagnetic (EM) energy.

Radar cross‐section reduction by polarization rotation
Microwave and Optical Technology Letters, 1995AbstractA system formed by a cascade connection of meander‐line strip grating surfaces that rotates the polarization plane of a linearly polarized wave is reported and measured. Reflectivity measurements of the system shaped on a reflector‐backed metallic ground plane have shown reflectivity levels smaller than –20 dB over the 10.5–17‐FHz band.

In this chapter we presented the four basic techniques for RCS reduction. Of the four, the use of shaping and radar absorbers are by far the most effective. As the design and use of RAM is covered in detail in Chapter 8, this chapter focuses on the fundamentals of shaping for RCSR.

The radar cross section reduction of microstrip patches
Proceedings of IEEE. AFRICON '96, 2002The radar cross section (RCS) reduction of microstrip patch antennas for low-observable platforms is considered, with emphasis on the application of lossy superstrates. The observed effect of these on antenna parameters is related to expected RCS reduction using results from the literature.

Radar Cross Section Reduction by Absorber Covering
Journal of Electromagnetic Waves and Applications, 1989Radar cross section (RCS) reduction by absorber covering is experimentally studied by employing microwave diversity imaging. Experimental results show that broadband absorber covering is not effective at reducing the co-polarized (the transmitting and receiving antennas have opposite sense of circular polarization) RCS of a plate when the incident wave

Active Radar Cross Section Reduction
2015This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in ...

Reduction of radar cross section of metallic cylinders
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990A method for RCS (radar-cross-section) reduction of metallic cylinders using periodic strip grating techniques is presented. The RCS of a cylinder with a periodic strip-loaded dielectric surface (SLDS) is determined experimentally and is compared with a reference target having the same dimensions. A typical reduction of 30-40 dB is obtained.
