Abstract
A combined RF/IR system in which a common surface is used in the dual modes of radiating and absorbing RF energy and of reflecting and focusing IR energy. The common surface is structured, configured, and used as the slotted array antenna for the RF energy and as the primary mirror of a Cassegrain optical subsystem for the IR energy.
Claims7
A dual mode radio frequency-infrared frequency seeker system, comprising:
- a. means for seeking, sensing, radiating and absorbing radio frequency energy, wherein this means is mounted on a gimbal means and includes a radio frequency antenna having a surface;
- and
- b. means for seeking, sensing, reflecting, and focusing infrared frequency energy, wherein this means is also mounted on said gimbal means and includes a Cassegrain infrared frequency optical subsystem having a primary mirror with a surface, and wherein this means is operably associated with and is in coaxial relationship with said means for seeking, sensing, radiating and absorbing radio frequency energy;
- and wherein said surface of said radio frequency antenna and said surface of said primary mirror are the same surface and form a surface common to both said means, said surface common to both said means defining a strip line transmission assembly, said strip line assembly including a front ground plane and a rear ground plane and being configured in a parabolic shape and having a stip transmission line disposed between said front ground plane and said rear ground plane.
