In this paper we present the test and validation results for the RCS of spherical objects derived by using conformal finite difference time domain (CFDTD) technique, which was introduced for obviating the staircasing errors introduced by the conventional finite difference time domain (FDTD) approach when dealing with curved bodies. We demonstrate that the CFDTD results show significant improvement in accuracy over those derived by using the conventional FDTD that employs a staircasing of the sphere geometry.
