ATI's Principles Of Modern Radar course


Share |

Summary

Modern radar and its related topics, architectures, technologies, and applications are covered, from fundamentals to the current state of the art in each area. Surface and airborne radars are described: each with its specific challenges. Conventional and advanced topics are introduced, including ESA and AESA, Auto-calibration of active phase arrays, modern waveforms and tracking, synthetic aperture radar and synthetic wideband, adaptive cancellation and STAP, radar phenomenology, modeling and simulations, key challenges and supporting state of the art technologies. This course is designed to benefit both engineers and technical managers.

Instructor:

    Dr. Menachem Levitas received his BS, maxima cum laude, from the University of Portland and his Ph.D. from the University of Virginia in 1975, both in physics. He has forty one years experience in science and engineering, thirty three of which in radar systems analysis, design, development, and testing for the Navy, Air Force, Marine Corps, and FAA. His experience encompasses many ground based, shipboard, and airborne radar systems. He has been technical lead on many radar efforts including Government source selection teams. He is the author of multiple radar based innovations and is a recipient of the Aegis Excellence Award for his contribution toward the AN/SPY-1 high range resolution (HRR) development. For many years, prior to his retirement in 2011, he had been the chief scientist of Technology Service Corporation / Washington. He continues to provide radar technical support under consulting agreements.
