Digital Beam Forming and nulling are viable means of GPS array signal processing that enable multipath mitigation and provide protection against interference. As reported in the literature [1], nulling causes errors in the carrier phase and code phase measurements. The output of multi element antenna arrays (Controlled Reception Pattern Antennas -CRPAs) are subject to significant variations in their phase patterns that arise from the application of time varying adaptive array weights. This phase error can be compensated in the carrier phase tracking domain in the baseband GPS receiver. Classical approaches implement a constrained beam steering mechanism to control the phase response of the array in the look direction. An alternative approach using unconstrained adaptive array processing with compensation for the subsequent phase distortion of the GPS signal is demonstrated using a software defined GPS radio.

“…The performance of each beamforming method can be applied to different antenna array configurations. The antenna elements are put together in a known geometry, which is usually uniform -Uniform Linear Arrays (ULA), Uniform Rectangular Arrays (URA) or Uniform Circular Arrays (UCA) (Ioannides & Balanis, 2005;Moelker, 1996). Two configurations, URA and UCA, with the elements extended in two dimensions enable to control the beam pattern in both azimuth and elevation, and for that reason they can be used for implementation of beamforming in GPS receivers.…”

A two-stage blind adaptive anti-jamming algorithm for global positioning systems (GPS) is proposed in this study. The new algorithm cancels interferences by projecting the array received signals on the orthogonal complement space of interferences. Then the algorithm utilises the CLEAN method to estimate direction of arrivals of GPS signals according to the period repetitive feature of GPS coarse/acquisition (C/A) code and form the multi-beam, where each beam can point one GPS signal. Test data and simulation results show the effectiveness of the new algorithm.
