ATI's Radar Systems Design & Engineering course

Summary: This four-day course covers intermediate level radar functionality, architecture, and performance. Diverse issues such as transmitter stability, antenna pattern, clutter, jamming, propagation, target cross section, dynamic range, receiver noise, receiver architecture, waveforms, processing, and target detection are treated in detail within the unifying context of the radar range equation, and examined within the contexts of surface and airborne radar platforms. The fundamentals of multi-target tracking principles are covered, and detailed examples of surface and airborne radars are presented. This course is designed for engineers and engineering managers who wish to understand how surface and airborne radar systems work, and to familiarize themselves with pertinent design issues and the current technological frontiers. Instructors: Dr. Menachem Levitas is the Chief Scientist of Technology Service Corporation (TSC) / Washington Operation. He has 33 years of experience, 25 of which include radar systems analysis and design for the Navy, Air Force, and FAA. He holds the degree of Ph.D. in physics from the University of Virginia. He has worked extensively on the AEGIS radar system, and has had significant experience with many other existing and national Navy, Air Force, and Foreign radars. He has performed the radar suite tradeoff analysis for the DD 21 radar program which included Counter Fire considerations in support of the US Marine Corps requirements. He is the recipient of the AEGIS Excellence Team Award for his contributions for the AN/SPY-1 radar High Range Resolution (HRR) Development. Stan Silberman is a member of the Corporate Staff of TSC/Washington. He has 31 years of experience in radar systems analysis and design for the Navy, Marine Corps, Air Force, and FAA. In support of Navy programs, he has performed analysis and developed simulations on the AN/SPS-49 and AN/SPY-1 radar, as well as multisensor tracking systems such as AN/SYS-1 and -2. Marine Corps support has included performance assessment of the AN/TPS-59 and AN/TPS-63 radars and simulation and analysis of the multisensor tracker in TAOC. His areas of specialization include automatic detection and tracking systems, sensor data fusion, simulation, and system evaluation.
