Aperture Maximization with Half-Wavelength Spacing, via a 2-Circle Concentric Array Geometry that is Uniform but Sparse

Kinyili, Musyoka; Kitavi, Dominic Makaa; Ngari, Cyrus Gitonga (Journal of Advances in Mathematics and Computer Science, 2019-05-25)

This paper proposes a new sensor-array geometry (the 2-circle concentric array geometry), that maximizes the array’s spatial aperture mainly for bivariate azimuth-polar resolution of direction-of-arrival estimation ...
Cramer-Rao Bound of Direction Finding Using Uniform Arc Arrays

Nyokabi, Veronicah; Kitavi, Dominic M.; Ngari, Cyrus G. (2019)

Direction-of-Arrival estimation accuracy using arc array geometry is considered in this paper. There is a scanty use of Uniform Arc Array (UAA) in conjunction with Cram er-Rao bound (CRB) for Direction-of-Arrival estimation. ...
