In this paper, an absorber with a resistive film is proposed, which holds stable polarization absorption characteristics at large angles by exploring the principle of structure. The contains three layers: top layer metal patch film, and middle covered patch. thickness structure only 0.5 mm, can be perfectly attached to trihedral corner reflector (TCR) without affecting reflector. By laying on T...

The radar cross sections (RCS) of both small and large ships for High Frequency Surface Wave Radar (HFSWR) were studied by using Numerical Electromagnetics Code [4] and by using measurements from a HFSWR system at Cape Race, Newfoundland, Canada. The results of the study indicate that Teleost, a 2405-ton Canadian Coast Guard ship, and large cargocontainer vessels (~36000 ton) have comparable RC...

In this contribution, an accurate description of the ocean backscatter from a probability density function is proposed. The Elfouhaily spectrum has been used to generate a realistic sea surface. The scattering field will be computed by using the Physical Optics (PO). The K distribution has been already used to characterize the Radar Cross Section (RCS) of the sea surface. However, the probabili...

The article explores methods for detecting and tracking air targets in radar with an artificially reduced cross-section (RCS). A technique control the antenna system using adaptive method is presented, which based on adapting to conditions of information uncertainty due fluctuations excitation signal target's radar-absorbing coating. Known aircraft (active passive, do not take into account stru...

One platform that is currently highly developed as an air defense technology the Unmanned Combat Aerial Vehicle (UCAV) which a UAV system equipped with weapon or has combat capabilities. In this study, UCAV concept was aim of having stealth low observability aspect by being shown to have Radar Cross Section (RCS) value. And in paper model generic configuration NATO STO/AVT-161 task group, namel...

The emergence and popularization of various fifth-generation fighter jets with supersonic cruise, super maneuverability, stealth functionalities have raised higher more comprehensive challenges for the tactical performance operational indicators air defense weapon systems. training systems requires simulated targets; however, traditional targets cannot simulate radar cross-section (RCS) distrib...

Abstract SAR(Synthetic Aperture Radar) images of sea targets are great significance to the military. In view high cost obtaining measured data SAR images, this paper implements a target image simulation method based on electromagnetic scattering calculations. This uses Phillips spectrum generate surface geometric model, and combines model model; then SBR(Shooting Bouncing Rays) calculate target...

In this paper, we apply the Shannon wavelet basis functions to the method of moments to evaluate the radar cross section (RCS) of the conducting and resistive surfaces. The problem is modeled by the integral equations of the first or second kind. An effective numerical method for solving these problems based on the moments method and using Shannon wavelet basis functions is proposed. The validi...

In this paper, a novel moment-matching reduced order model technique termed the multi-dimensional well-conditioned asymptotic waveform evaluation (MDWCAWE) method is presented. The MDWCAWE method can be used to efficiently determine the radar cross section (RCS) of arbitrarily shaped objects, in both the frequency and angular domains simultaneously. Numerical results are given in order to demon...
