A dual mode RF/IR seeker suitable for use in an anti-radiation missile is disclosed. The infrared sensor is responsive to radiation within the 4.0 to 4.8 micron band and the radio frequency sensor is responsive to radio frequency signals within a 6.5 to 16.5 GHz band. The infrared sensor comprises a folded Cassegrainian telescope arrangement, including a primary mirror which is transparent to radio frequency energy. The radio frequency sensor comprises an annular array of orthogonally disposed stripline flared notch radiating elements. A broadband microwave receiver, fabricated in a multilayered stripline package, is provided for forming radio frequency monopulse sum' (E) and difference (A) signals and for converting such radio frequency monopulse signals to suitable intermediate frequency signals for processing in an I.F. receiver.

A polarization compensating device useful in correcting radome-induced polarization errors in a linearly polarized antenna in a missile is described.

Polarization compensating device for antenna within a radome

A copper plated styrofoam dielectric planar array antenna having adjacent otted waveguide sections bonded with a silver loaded conducting epoxy. The sections are fabricated by plating a thin film of copper on a preformed styrofoam dielectric material. The slots are machined into the copper plated sections.
