Advances in the Theory and Implementation of GNSS Antenna Array Receivers

Summary

The ninth chapter, Advances in the theory and implementation of GNSS antenna array receivers, by Javier Arribas, Pau Closas, and Carles Fernández‐Prades, from CTTC, Spain, and Manuel Cuntz, Andriy Konovaltsev, Michael Meurer, from DLR (German Aerospace Center), Germany, focuses on recent developments in the field of antenna arrays applied to the design of robust, high‐performance Global Navigation Satellite System (GNSS) receivers. This work mainly focuses on the architecture of a GNSS receiver with an adaptive antenna array. The specifics of the design of such receivers are discussed, covering both analog and digital signal processing blocks. Special attention is devoted to the design ofcritical components such as the antenna array, radio frequency (RF) front‐ends and analog‐to‐digital (A/D) converters. Array signal processing techniques are also addressed describing two main strategies based on (i) the spatial filtering by means of digital beamforming and (ii) signal parameter estimation by statistical array processing. Finally, two operational prototypes of GNSS receivers with adaptive antennas are proposed, including their latest test results.
