A very accurate model for backscattering by right angled dihedral corners

An accurate model for backscattering by a perfectly conducting 90 degrees dihedral corner is presented. This model has been obtained by adding to the IPO (improved physical optics) model the PTD (physical theory of diffraction) contribution, and makes it possible to accurately predict the monostatic radar cross section of the corner in a plane normal to its wedge. Representative results are 5.67 in the case of normal polarization.<
