Abstract

A radar system with a main antenna that is rotatably supported to permit use in searching about a search axis includes an auxiliary antenna that is rotatably supported to permit use in complementing main antenna coverage. Rotational components and control circuitry are provided, both for simultaneously rotating the antennae with the auxiliary antenna poised in position relative to the main antenna to stop and face a direction just searched, and for separately stopping the auxiliary antenna in position to face a selected direction as rotation of the main antenna continues. One embodiment includes a coaxially-masted antenna support having a pair of coaxial masts mounted on a common support structure, one mast being rotatably mounted to support the main antenna and the other mast being fixed. A carriage is rotatably mounted on the coaxial masts to support the auxiliary antenna. One clutch mechanism selectively interconnects the carriage and the rotatable mast to cause them to rotate together and another clutch mechanism selectively interconnects the carriage and the fixed mast to cause carriage rotation to stop.
