About the Event

Emerging mission areas such as military operations in urban and mountainous terrain, border surveillance, and maritime domain awareness are stressing the current RF technology base. New requirements such as detection and tracking of small, slow moving targets, very high revisit rates, steep grazing angles, high clutter, RF interference mitigation, and multi-mission operation impose new challenges for the next generation of RF sensor systems. In addition, the need for persistent surveillance is motivating a shift towards small unmanned air vehicles with difficult payload constraints on size, weight, power, and cost. This talk will describe work that is currently underway at MIT Lincoln Laboratory to develop and demonstrate critical enabling technologies for the next generation of advanced RF sensors, including wideband conformal dual-polarized apertures, reconfigurable T/R modules, digital subarray beamformers, compact wideband high dynamic range receivers, and adaptive RF preconditioning networks. The talk will conclude with a discussion of new applications and technology challenges on the horizon.


Jeffrey S. Herd received the B.S., M.S. and Ph.D. degrees in Electrical Engineering from the University of Massachusetts, Amherst, in 1982, 1983 and 1989, respectively. From 1983–1999, he was with the Antenna Technology Branch of the Air Force Research Laboratory at Hanscom AFB, MA. From 1992-1994, he was a visiting scientist with the Antenna Group of the Institute for High Frequency Physics, German Aerospace Research Establishment (DLR), Wessling, Germany.. In 1999, he joined MIT Lincoln Laboratory, Lexington, MA, where he is currently an Assistant Group Leader in the Advanced RF Sensing and Exploitation Group. MIT Lincoln Laboratory conducts research and development aimed at solutions to problems critical to national security. The Advanced RF Sensing and Exploitation Group is developing advanced RF technologies and adaptive signal processing techniques for next generation RF surveillance systems. Dr. Herd’s research interests include ultra-wideband arrays, RF pre-conditioning networks, multifunction T/R modules, digital sub-array architectures, and wideband digital receivers. He currently leads the RF hardware risk reduction effort for the Multifunction Phased Array Radar Program (MPAR) at MIT. Dr. Herd was the Chairman of the Boston Chapter of AP-S from 1990-1991, and served on the Executive Committee of the IEEE Boston Section from 1996-1998. He was the General Vice-Chairman for the 2001 IEEE AP-S/URSI Symposium in Boston, MA.
