RCS values of dihedral and triangular trihedral corner reflectors.
What is your question?
What is RCS value of triangular trihedral corner reflector?
The RCS of a dihedral CR is given by 8 * pi * w ^ 2 * h ^2 / wavelength ^ 2 (i.e. 8 * pi * square of the width * square of the height / square of wavelength. So for a dihedral of width and height of 1.5m and a frequency of 5.405 GHz (for S1), the RCS is 46.17 dB.
The RCS of a trihedral CR is given by (4/3) * pi * length ^ 4 / wavelength ^ 2. So for a triedral of length 2.5m for S1, the RCS is 47.26 dB.
