WebMay 1, 2009 · Abstract. Trihedral corner reflectors are the preferred canonical target for SAR performance evaluation for many radar development programs. The conventional trihedrals have problems with substantially reduced Radar Cross Section (RCS) at low grazing angles, unless they are tilted forward, but in which case other problems arise.

They offer the following desirable attributes. …
WebJan 6, 2012 · The sensor-target orientation plays an important role in the detection of cubical objects (i.e. buildings), that is, the RCS (radar cross section) is a strong function of azimuth and elevation angles in the SAR imaging coordinate system. 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.
