A radio frequency antenna array uses multiple lenses, and mechanically movable elements, to provide ground-based and sky-based coverage for multiple object communication and tracking. The antenna array includes at least two spherical lenses, where each spherical lens has at least two associated RF elements. A third lens is added, along with at least two additional RF elements to narrow and track the overlapped beams from the first and second lenses. Each lens also includes a sub-controller configured to adjust a phase of the signals produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically configure the phase shifter to modify a phase of the output signals from the elements based on the relative positions between the RF elements. The overlapped beams track independent targets, such as satellites, across an area.

An aircraft nose radome has a first portion that is transparent to X band microwave energy, and a second portion that is transparent to W band microwave energy. The second portion may be an insert that is secured to the radome at an opening formed therein. The insert may have a multi-layer structure with first, second and third layers, a fourth layer of foam between the first and second layers, and a fifth layer of foam between the second and third layers. The insert may include a plurality of spaced-apart, elongated reinforcing members or ribs between the first and second layers and between the second and third layers that extend along a longitudinal direction defined by the insert. The insert may have a serrated cross-sectional configuration.
