摘要

The parabolic equation (PE) method gives accurate results in calculation of scattering from objects with dimensions ranging from one to tens of wavelengths. Solving parabolic equation with the marching method needs limited computer storage even for scattering calculations of large targets. In this paper, the calculation procedure of radar cross section using scalar three dimensional parabolic equations is considered and the necessary equations are derived. In order to show the capabilities of the method two structures are analyzed. First scattered fields and RCS of an airplane in the forward direction are computed. Next, scattered fields and RCS of a reflector antenna in the backward direction are calculated. The obtained results are compared with physical optics results.
