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.

Abstract: An air vehicle, such as a munition like a guided bomb or missile, has a control system that allows control surfaces to be mechanically uncoupled from one or more actuators to allow the control surfaces to freely move (rotate) relative to a fuselage of the vehicle, for example allowing the control surfaces to “weather vane” by assuming an orientation corresponding to the direction of airflow past the air vehicle (direction of airflow relative to the air vehicle). When active positioning of the control surfaces is desired, the control surfaces may be mechanically coupled to one or more actuators that are used to position the control surfaces. The selective coupling of the actuator(s) and the control surfaces may be accomplished by selectively coupling together a sleeve that is mechanically coupled to the control surfaces, and a nut that moves along a shaft of an actuator, for example using a resilient device.

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.
