Calibration CORDIC Measurement accuracy Phased array
The beamforming performance of a phased array is determined by the amplitude and phase relationships; however finite manufacturing tolerances and environmental effects cause imbalances in these relationships. These imbalances can be addressed by a calibration scheme. Normally such calibration schemes require either a known or unmodulated pilot signal, thereby interrupting service. In this paper we present a novel approach utilising the CORDIC algorithm to allow for collaboration with modulated data streams.
