An alignment apparatus configured to be mounted to a radar array antenna having a generally planar face for aligning the antenna includes a rigid frame defining a plane generally parallel to the face of the antenna when the rigid frame is mounted to the antenna. A flexible member is associated with the rigid frame and is configured to flex relative to the rigid frame. The apparatus further includes an optical source for emitting a light beam and a target. One of the optical source and the target is associated with the flexible member and the other of the optical source and the target is associated with the rigid frame. A distance between the path of the light beam and the target is indicative of the degree of misalignment between the flexible member and the rigid frame.

Antenna alignment fixture

A mobile, telescoping radar array is disclosed. In some embodiments, the radar array has a plurality of support stages that fully nest when stowed and assume a telescoped form when deployed. A plurality of radiating elements depend from each stage. The support stages, as deployed, have a geometry that supports 360 degrees of radar coverage without rotating or otherwise repositioning the radar array.

Telescoping radar array

The present invention provides an antenna system for transmitting and receiving radar signals comprising a first non-conductive material embedding a plurality of parasitic antenna elements, where the first non-conductive material interfaces a second non-conductive material embedding a plurality of electrical feed elements, and wherein the first non-conductive material covers one or more adjacent interconnecting joints.
