James K Beard, Costas arrays and enumeration to order 1030, IEEE DataPort, 2017. [Online, downloadable, free]. DOI: 10.21227/H21P42.

Beard, J.K., Characterization of Rotating and Spinning Bodies with Quaternions, Presented at the Philadelphia Section IEEE meeting, February 21, 2017. Link: slides (2.4 MB PDF file). Other files related to this presentation are on this web site here.

Beard, J.K., Planar Array Design and Performance, June 26, 2014. Presented at a meeting of the Philadelphia IEEE Signal Processing Chapter, co-sponsored by the Aerospace and Electronic Systems Chapter. Link: slides (20 MB ZIP file). This paper is the original release of a high performance Bayliss weighting with a three-parameter design, as opposed to the classical two-parameter Taylor and Bayliss weighting.

A binary to generate Taylor and Bayliss weightings, and the source code for a Fortran 2003 module that contains procedures to compute Taylor and Bayliss weightings for your program are both available for download here.

Jon C. Russo, Keith G. Erickson, and James K Beard, Costas array search technique that maximizes backtrack and symmetry exploitation, CISS 2010, March 17, 2010, Princeton University, Session WA-04, Paper 6; links: paperslidesaddendum slides.

Konstantinos Drakakis, Scott Rickard, James K Beard, Rodrigo Caballero, Francesco Iorio, Gareth O'Brien and John Walsh, Results of the enumeration of Costas arrays of order 27, IEEE Transactions on Information Theory, 54, 10 (October 2008). [The Drakakis group at University College, Dublin, Ireland, announces completion of an exhaustive search over order 27 in this paper. They made their announcement to the community by email on May 23, 2008 but did not notice the only new Costas array of that order in a log file dated March 9; the group of Beard, Russo, Erickson, Monteleone and Wright announced this new Costas array a few days after the Konstantinos group made their announcement; their log file indicates that this array appeared in their logs on April 7 in a processor node provided by Keith Erickson. The Beard team announced the discovery of this Costas array by email on May 29, 2008.]
