Recent Research Papers:

Here are a handful of recent publications (the links are to pdf versions of the papers):
M. A. Richards, “Coherent Integration Loss due to White Gaussian Phase Noise,” IEEE Signal Processing Letters, vol. 10, no. 7, pp. 208-210, July 2003.

M. A. Richards, D. P. Campbell, and K. M. Mackenzie, “Morphware Stable Interface: A Software Framework for Polymorphous Computing Architectures,” Digest of Papers, 2003 Government Microcircuits Applications Conference (GOMAC).

W. W. Bonifant, Jr., M. A. Richards, and J. H. McClellan, “Interferometric height estimation of the seafloor via synthetic aperture sonar in the presence of motion errors”, IEE Proceedings - Radar, Sonar, and Navigation, vol. 147, no.6, pp. 322-330, Dec. 2000. Based on Will Bonifant’s M.S. thesis at Georgia Tech, this paper was subsequently awarded the Clarke Griffiths Memorial Premium prize by IEE in July 2002.




Books and Book Chapters:

I haven’t written any books (yet), but I have edited or contributed chapters to a few:

MATLAB™ Software:

Finally, here are a couple of possibly useful sets of MATLAB M-files available for download. Each is a WinZip archive. T he sonar simulation includes a README file and supporting documents; the detection calculator is reasonably self-explanatory based on the header comments in the M files and the two example “driver” M-files included.
THIS SOFTWARE IS PROVIDED “AS IS” WITH NO EXPRESS OR IMPLIED WARRANTY OF SUITABILITY FOR ANY PURPOSE WHATSOEVER. IT IS AVAILABLE FOR USE SUBJECT ONLY TO THE REQUIREMENT THAT ALL SOURCE CREDITS INCLUDED IN THE FILES BE RETAINED IN ALL COPIES AND DERIVATIVE WORKS.
Probability of Detection calculator for nonfluctuating and fluctuating (Swerling models 1-4) targets, based on Meyer and Mayer equations.

2D and 3D synthetic aperture sonar simulation developed by William W. Bonifant, Jr., as part of his M.S. thesis at Georgia Tech.
