摘要

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.
