Abstract

A dual reflector objective design is explored in WR3.4 for sensing of spherical targets. The secondary mirror shadow enables coaxial integration of topical systems without additional obscuration of the submillimeter wave beam. The system is designed with geometrical optics and evaluated with physical optics. The power coupling efficiency between the source electric field and back scattered field from a spherical target is >0.4 across the frequency of interest.
