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. WebProSensing trihedral corner reflectors are machined with high precision to provide accurate known (calculated) Radar Cross Section (RCS) targets. Applications are a variety of radar testing and characterization. Due to their geometry, these passive devices offer the highest possible RCS of any object per unit volume.
Webeach trihedral CR, acquired using a differential GPS unit, as well as the theoretical Radar Cross Section (RCS), were compared to the latitude, longitude, and RCS values computed using VUSAR. The RCS comparisons were within 3 dB of each other while the latitude and longitude errors were relatively consistent within each acquisition.
