A polarization-sensitive geometrical theory of diffraction technique for numerical evaluation of radar targets

Two-dimensional scalar geometrical theory of diffraction techniques are extended to provide a polarization-sensitive method to evaluate three-dimensional complex targets. The method tracks field strength and polarization separately, providing the monostatic radar return in terms of the spatial field distribution that represents the target depth. The technique numerically evaluates a geometrically complex object with perfectly conducting surfaces that is surrounded by an isotropic homogeneous medium. Expressions are developed to emphasize the diffraction-induced phase shift as well as the spatial distribution´s correspondence to the depth of target.<>
