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. 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.
