Abstract :
The efficient evaluation of scattering cross section (SCS) of targets located above a half space is investigated using the reciprocity theorem and the spatial dyadic Green´s function (SDGF) obtained via the discrete complex image method with generalised pencil function. The numerical results showed that the SDGF is accurate not only in the near and intermediate field region, but also the SCS in the far field.
