Abstract

Abstract

Dielectric conformal dome phased array antenna uses the dielectric dome to change the direction of the scanning beam. It is supposed to widen the scan-range of planar phased array to half spherical space or more. It is suitable for missiles and air-borne radars. When analysise its scanning characteristics, the divergence factor(DF) of the dome must be calculated. This paper provides two methods to study the DF which are based on geometrical optics, and compares them. These methods are very useful in studying the reflection and the refraction of the non-planar layered dielectric.
