PO-based Shaped Reflector Design for Sectoral Pattern RADAR Antenna

In this paper, an automatic procedure based on physical optics (PO) for the design and optimization of a sectoral pattern shaped reflector at millimeter waves is proposed. As a starting guess for the PO-based iterative procedure, a fast optimization based on geometrical optics (GO) has been developed. In order to preserve the smoothness of the reflector shape, a reduced set of control points on its surface is defined, and an interpolation is performed between them. The results show the effectiveness of the proposed technique, that can profitably find applications in the design of RADAR antennas for surveillance purpose.
