Radar cross-section of thin dielectric bodies

The radar cross-section of a thin dielectric ellipsoid of arbitrary size is derived. The solution is obtained by employing a quasistatic approximation to find the field inside the ellipsoid. Techniques described in the literature were used to determine the fields scattered by the ellipsoid in the far zone. The scattered-field relationships were then used to obtain the radar cross-section equations in closed form. The solution for the radar cross-section obtained in this manner was compared with available results in the literature and agreement was found.
