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. WebNov 2, 2011 · The triangular pyramidal trihedral ACR is the most geometrically stable ACR, and has the highest tolerance towards incident radar ray’s deviation. Its RCS values, however, are the least of the three. Due to the high cost of deploying ACRs in the fields, the physical optics method seems to provide a viable way to choose appropriate ACRs. kappa sneakers south africa
