Query: A beamforming approach to the self-calibration of phased arrays   In this paper, we propose a beamforming method for the calibration of the
direction-independent gain of the analog chains of aperture arrays. The gain
estimates are obtained by cross-correlating the output voltage of each antenna
with a voltage beamformed using the other antennas of the array. When the
beamforming weights are equal to the average cross-correlated power, a relation
is drawn with the StEFCal algorithm. An example illustrates this approach for
few point sources and a 256-element array.
