In the course of designing and optimizing arrays, many difficulties are often experienced. Due to the complex nature of modern arrays, finding the optimal configuration from scratch can be a challenging task. Many synthesis options are available for certain array types, however they are not without their problems as well. This paper will deal with a technique for optimizing an array using Bayesian sampling and inference techniques. This technique can be applied to any array with any configuration to determine the best fitting parameters for a given radiation pattern. Also to be discussed includes how the procedure is implemented in a modern programming methods and its applicability to parallelization. Results will show that this method allows for the examination of an entire parameter space so that the best parameters for an arbitrary linear array can be quickly and efficiently examined.


Dr. Atef Z Elsherbeni - University of Mississippi

Atef Z. Elsherbeni received an honor B.Sc. degree in Electronics and Communications, an honor B.Sc. degree in Applied Physics, and a M.Eng. degree in Electrical Engineering, all from Cairo University, Cairo, Egypt, in 1976, 1979, and 1982, respectively, and a Ph.D. degree in Electrical Engineering from Manitoba University, Winnipeg, Manitoba, Canada, in 1987. He was a Research Assistant with the Faculty of Engineering at Cairo University from 1976 to 1982, and from 1983 to 1986 at the Electrical Engineering Department, Manitoba University. He was a part time Software and System Design Engineer from March 1980 to December 1982 at the Automated Data System Center, Cairo, Egypt.
