Abstract: A radome structure of an antenna system is provided having a plurality of switchable antenna elements disposed around a perimeter of the radome structure that can simultaneously track multiple targets and be implemented in a variety of different applications. Each of the switchable antenna elements can be individually switched between different radiation patterns to support different applications. The antenna system may include an infrared (IR) sensor pedestal, an IR sensor disposed on the IR pedestal and a plurality of switchable radio frequency (RF) antenna elements disposed in a circumferential direction around the IR sensor pedestal. In an embodiment, each of the plurality of switchable RF antenna elements can be switched from a first radiation pattern to a second radiation pattern to change an array radiation pattern of the antenna.

Abstract: A dual-mode active and passive gimbaled optical system including a mechanism for coupling an optical signal from an off-gimbal active-mode source into the on-gimbal passive-mode optical path. One example of the system includes a passive off-gimbal detector assembly configured to image emissive electromagnetic radiation from a viewed scene, and a receiver-path optical assembly, including on-gimbal objective optics, that directs the electromagnetic radiation to the off-gimbal detector assembly. The system further includes an off-gimbal active source that generates an optical signal, a gimbal bearing assembly that supports rotation of the gimbal and includes a centrally-located output ferrule mated to an optical fiber that transports the optical signal from the active source to the output ferrule, and an on-gimbal optical coupling element that receives the optical signal from the output ferrule and couples the optical signal into the receiver optical path to direct the optical signal toward the on-gimbal objective optics.

Abstract: The present disclosure is directed to a seeker system having an infrared (IR) sensor pedestal, an IR sensor disposed on the IR pedestal and a plurality of radio frequency (RF) antenna elements symmetrically disposed in a circumferential direction around the IR sensor pedestal. The seeker system further includes a plurality of RF waveguiding structures. In an embodiment, each of the RF waveguiding structures have first and second ends and are symmetrically disposed in a circumferential direction around the IR sensor pedestal such that in response to an RF signal incident on a first end of the waveguiding structure, the RF signal is provided to one of the plurality of RF antenna elements such that in response to an RF signal incident on the seeker system from any direction, each of the plurality of RF antenna elements receive the RF signal with a desired phase characteristic.
