Backscattering reduction of corner reflectors using scs technique

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...

Effects 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...

Corner Reflectors - A New Concept of Imaging Vertical Boundaries

Corner Cube Reflectors by Surface Tension Self-Assembly

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...

External Calibration of Millimeter-Wave Atmospheric Radar Systems Using Corner Reflectors and Spheres

Millimeter-wave (MMW) radars have become standard cloud research tools because of their high sensitivity to small cloud particles, low prime power requirements, and compact size. However, MMW radars are more likely to suffer gain variations, so their calibration becomes crucial. Radar systems can be calibrated absolutely by various methods such as measurements of individual system parameters, c...
