Computer Model for the Transmission Characteristics of Dielectric Radomes

摘要

The electric far field radiation pattern is determined for a uniformlyilluminated, linearly polarized circular aperture transmitting through a dielectric radome located in the near field of the aperture. A modified electric field integral equation is solved using the method of moments procedure and the thin shell approximation for dielectrics. The resulting solution was computer coded for ogive and spherical radome shapes. The program is designed in a modular fashion to accommodate the addition of different antenna types, illumination functions or radome shapes.
