Abstract: An antenna system comprises a reflector subsystem, a rotatable support structure and a support member. The reflector subsystem receives an input beam and reflects the input beam to produce an output beam steered in elevation by an elevation reflector and in azimuth by an azimuth reflector, towards a target. The rotatable support structure is operably coupled to the azimuth reflector and to the elevation reflector and is configured to rotate them simultaneously. The support member comprises a lengthwise portion coupled to the rotatable support structure and an offset portion coupled to the elevation reflector, the offset portion configured to offset the elevation reflector from the lengthwise portion. The offset portion is configured to enable clearance of the elevation reflector during beam steering of the output beam to extreme ends of a range of motion of the elevation reflector.

Abstract: A system and apparatus is provided for a modular radar system. The modular radar system can include a plurality of radar system modules that can be detachably coupled and can include a configurable number of radio-frequency (RF) transmit and receive assemblies. The RF transmit and receive assemblies can include radiating element(s) that emit electromagnetic radiation. The plurality of radar system modules can also include at least one processor coupled to control power of the electromagnetic radiation and/or at least one controller to control the RF transmit and receive assembly, the power unit and the digital receiver and exciter module, at least one digital receiver and exciter to convert RF to digital in receive mode, and digital to RF in transmit mode, and/or at least one RF beamformer to generate one or more RF beams.
