This paper proposes a-element uniform circular array (UCA)-beam multibeam beamformer
having arithmetic complexity. The architecture achieves a reduction of the arithmetic …

Polygonalized phased arrays are a compromise between planar arrays and cylindrical
arrays that provide surveillance radar systems improved surveillance time from a convenient …

Circular and cylindrical arrays are advantageous when 360-degree azimuthal coverage is
desired, as they do not suffer the angle-dependent beam broadening and scan loss …

Circular arrays offer many advantages over traditional linear and planar arrays in modern
radar systems. The circular geometry facilitates design of omnidirectional, sector, and/or …

The modularization of 28 GHz multi-mode circular arrays and 60 GHz phased sub-arrays
onto N-sided convex polygons is presented. This includes a study on the basic impact of …

The Low-Band Radio Frequency RF Intelligent Distribution Resource LowRIDR concept
divides the architecture into the front-end RF resources and the back-end digital resources …

Beamforming can provide huge array gains in large-scale antenna systems under the
condition that the channel state information (CSI) has been obtained by training signals …

In recent years, the Navy has looked to transition to multifunction array apertures to reduce
the size of” antenna farms” on ships' masts and other space constrained areas. Cylindrical …

Cylindrical phased arrays are an attractive aperture for radar applications due to their
steering-angle independent gain, beamwidth, polarization, sidelobe levels, and reflection …
