- TITLE:
-
Phase-shift steer a uniform circular array
in the Fourier-series domain
- AUTHORS:
- J. O. Coleman and W. M. Dorsey
- ABSTRACT:
-
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
steered beams.

- Presented to the 2017 IEEE Wireless and Microwave
Technology Conference (WAMICON 2017), Cocoa Beach FL, USA,
April 24-25, 2017.
- ERRATUM:
-
Section IIIB begins by referring to the "unsteered element pattern" but should refer instead to the "unsteered array pattern."
- NOTE:
-
We discovered only in July 2017 that this paper covers essentially the same steering technique:
B. Sheleg, "A matrix-fed circular array for continuous scanning," in Proceedings of the IEEE, vol. 56, no. 11, pp. 2016-2027, Nov. 1968.
