Rcs trihedral
WebA corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects waves directly towards the source, but translated.The three intersecting surfaces often have square shapes. Radar corner reflectors made of metal are used to reflect radio waves from radar sets. Optical corner reflectors, called corner cubes … WebPhysical optics (po) and the method of equivalent currents (mec) are used for the formulation and calculation of the backscatter cross section of both the triangular and square trihedral corner reflectors. Scattering from a trihedral corner reflector is dominated by single, double, and triple reflections by the interior walls. A physical optics integration …

WebApr 24, 2015 · The calculation method for obtaining scattering characteristics of corner reflectors is proposed. The method allows calculating the radar cross-section of corner reflectors for arbitrary aspect angles. The method proposes separating the smooth part of reflectors and some neighborhood of their edges (including that of inner edges). The … WebElectrically large triangle and octahedral corner reflectors are compared to small ones in terms of wavelength through the simulations, in order to explain dependence of RCS reduction on the size of the reflectors for a given geometrical deviation from orthogonality.

WebAbstract: Trihedral corner reflectors are widely used as calibration targets for imaging radars because of their large radar cross section (RCS) and extremely wide RCS pattern. An important source of uncertainty in the RCS of a trihedral sitting on a ground plane is the coherent interaction of the ground plane with the trihedral.
