چکیده
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 TCR, TCR stabilized 8–40 GHz in range incident angle ±20°, radar cross-section (RCS) reduction value fluctuates around 1 dBsm. Thus, RCS values frequency points 10 GHz, 15 35 are consistent achieve accurate regulation RCS. stability different frequencies achieved, essential for precise complex scatterer structures. effectiveness method was verified experiments using metamaterial absorbing unit film.

RCS Analysis and Reduction for Lossy Dihedral Corner Reflectors
The radar cross-section patterns of lossy dihedral corner reflectors are calculated using a uniform geometrical theory of diffraction for impedance surfaces. All terms of up to third order reflections and diffractions are considered for patterns in the principal plane. The surface waves are included whenever they exist for reactive surface impedances. The dihedral corner reflectors examined hav...
متن کاملEffects Analysis of Machining Tolerance on RCS of Corner Reflectors
Corner reflectors are widely applied to the precise monitoring of crustal deformation. As shown in recently, however, the machining tolerance of rectangle trihedral corner reflectors in the production and deploy process often results in the changes of RCS. The Radar Cross Section (RCS) of rectangle trihedral corner reflectors are calculated based on Physical Optics Method (PO), the objective of...

A method of fabricating micromachined Corner Cube Reflectors (CCRs) with high surface flatness and accurate control of mirror angle is demonstrated. A parallel, automated three-dimensional self-assembly process is presented, using bonded silicon-on-insulator material and out-of-plane rotation powered by the surface tension of thick photoresist pads. Precise alignment is achieved by minimising t...
متن کاملP3C.8 Radar Calibration Using a Trihedral Corner Reflector
Many useful methods for calibrating weather radars in the field and laboratory are summarized by Joe and Smith (2001) from presentations at the 2001 AMS Radar Calibration Workshop in Albuquerque, NM . Additional methods are described by Atlas (2002). Common external (full-system) calibration methods range from using metal spheres suspended from balloons to the use of solar radio emissions. Alth...
متن کاملNovel Absorbers Based on Wideband Antenna Array for Rcs Reduction
This study presents a novel wideband absorber for radar cross section (RCS) reduction. Unlike previous absorber designs that use multilayer lossy materials, this study proposes a design based on a planar antenna array that adopts a bowtie dipole structure as the unit cell. The complete design procedure was investigated by using examples for singleand dual-polarized incident wave designs. The me...
