Abstract: 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.

Abstract: 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.

Abstract: 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.
