ABSTRACT
The concept of distributed beamforming antenna systems has received some
attention in the literature, with the focus being on systems employing fixed
antenna geometries. Mobile fractionated systems comprise antenna
geometries that evolve over time, and therefore differ significantly from
these case studies. This paper considers mobile distributed beamformers by
first providing definitions for such systems, a taxonomic breakdown of the
types of distributed beamformers and finally considering the associated
system level requirements. These can be of assistance when determining if a
system being analysed is a distributed beamformer, thereby aiding in
determining whether the systems engineering is complete. Also discussed
are various synergies that are applicable for such systems. Finally, an
example case study is provided to illustrate some of the concepts and trade-
offs when considering such systems. The GNSS requirements of such a
system are also described.
