Radar designers suppress sidelobes in the radiation pattern of a phased array antenna in order to avoid picking up objectionable amounts of ground clutter and other spurious signals. Two‐way antenna patterns result from the product of the transmit array pattern times the receive array pattern. Radars often have sidelobe specifications for the two‐way pattern. The traditional approach to synthesizing a two‐way pattern is to prescribe low sidelobe tapers for the transmit and receive patterns then assume that the peak two‐way pattern sidelobe level equals the peak transmit pattern sidelobe level time the peak receive pattern sidelobe level. This talk presents several approaches to directly synthesize two‐way array factors. Examples include linear and planar arrays.

Haupt received the BSEE from the USAF Academy (1978), the MS in Engineering Management from Western New England College (1982), the MSEE from Northeastern University (1983), and the PhD in EE from the University of Michigan (1987). He is Professor of Electrical Engineering at the Colorado School of Mines and was an RF Staff Consultant at Ball Aerospace & Technologies, Corp., a Senior Scientist and Department Head at the Applied Research Laboratory of Penn State, Professor and Department Head of ECE at Utah State, Professor and Chair of EE at the University of Nevada Reno, and Professor of EE at the USAF Academy. He was a project engineer for the OTH‐B radar and a research antenna engineer for Rome Air Development Center early in his career. He is co author of the books Practical Genetic Algorithms, 2 ed., John Wiley & Sons, 2004, Genetic Algorithms in Electromagnetics, John Wiley & Sons, 2007, and Introduction to Adaptive Antennas, SciTech, 2010, as well as author of Antenna Arrays a Computation Approach, John Wiley & Sons, 2010 and Timed Arrays Wideband and Time Varying Antenna Arrays, Wiley, 2015. His newest book, Wireless Communication Systems: An Introduction, will be released in 2019. Dr. Haupt is a Fellow of the IEEE, Electromagnetics Academy, and Applied Computational Electromagnetics Society (ACES). He is an Associate Editor of the Ethically Speaking column for the Radio Science Bulletin and IEEE Antennas and Propagation Society Magazine.
