Abstract

The far-scattered field and radar cross section (RCS) are calculated by transforming the results of the transmission-line-matrix (TLM) method with the symmetrical condensed node (from the near-to the far-zone) by means of two different approaches, in the time domain. The first approach is based on the electromagnetic equivalence principle, and the second is based on the Kirchhoff theory of integration. Details and a complete description of the two approaches are given. Examples of far-zone-scattering results for three-dimensional conducting bodies are given to validate and compare the two methods
