In this work, two Gaussian Beam (GB) techniques were presented for investigating the radar cross section (RCS) of a cylinder with and without an aperture. Therefore, we have carried out experimental measurement of RCS of different PEC targets in the anechoic chamber. These measurements were used to validate the numerical results obtained using the GB approaches which are: Gaussian Beam Summation (GBS) and Gaussian Beam Launching (GBL). In the numerical simulation, the used GB techniques are firstly combined with the asymptotic Physical Theory of Diffraction (PTD) method. After that, the RCS results are evaluated with the Method of Moment (MoM) and also with the experimental measurements.
