A Hybrid-Analytical-Model for the Paraboloidal Reflector Antenna

In this paper, a computationally efficient method of moments (mom)-physical optics (po) formulation of the general paraboloidal reflector antenna problem is developed. the formulation hybridizes the integral equation approach characteristic of the conventional ‘low-frequency’ methods and the asymptotic solution of the wave-object interaction problem of po. this formulation is based on an adaptation of an approach prescribed by kerdemilidis - for a parametric description of the antenna’s geometry - leading to a generalization in a relatively simplified format of an ordinarily analytically involved process. the obtained results show a good agreement with the reported results due to other approaches and, consequently, prove the validity of the proposed model.
