Phase-shift steer a uniform circular array
in the Fourier-series domain
- J. O. Coleman and W. M. Dorsey
Taylor's 1952 Fourier series for a uniform circular
array's pattern here yields simple steering, with
minimal distortion, by applying a phase ramp to the
weights' DFT coefficients rather than to the weights
themselves as for a linear array. Computational
examples include steering a simple monopulse
difference beam created as the difference between

Section IIIB begins by referring to the "unsteered element pattern" but should refer instead to the "unsteered array pattern."
We discovered only in July 2017 that this paper covers essentially the same steering technique:
