ATI's Space Based Radar course
Synthetic Aperture Radar (SAR) is the most versatile remote sensor. It is an all-weather sensor that can penetrate cloud cover and operates day or night from space-based or airborne systems. This four-and-a-half-day course provides a survey of synthetic aperture radar (SAR) applications and how they influence and are constrained by instrument, platform (satellite) and image signal processing and extraction technologies/design. The course will introduce advanced systems design and associated signal processing concepts and implementation details. The course covers the fundamental concepts and principles for SAR, the key design parameters and system features, space-based systems used for collecting SAR data, signal processing techniques, and many applications of SAR data.
Bart Huxtable has a Ph.D. in Physics from the California Institute of Technology, and a B.Sc. degree in Physics and Math from the University of Delaware. Dr. Huxtable is President of User Systems, Inc. He has over twenty years experience in signal processing and numerical algorithm design and implementation emphasizing application-specific data processing and analysis for remote sensor systems including radars, sonars, and lidars. He integrates his broad experience in physics, mathematics, numerical algorithms, and statistical detection and estimation theory to develop processing algorithms and performance simulations for many of the modern remote sensing applications using radars, sonars, and lidars.
Dr. Keith Raneyhas a Ph.D. in Computer, Information and Control Engineering from the University of Michigan, an M.S. in Electrical Engineering from Purdue University, and a B.S. degree from Harvard University. He works for the Space Department of the Johns Hopkins University Applied Physics Laboratory, with responsibilities for earth observation systems development, and radar system analysis. He holds six United States and international patents, including the Delay/Doppler Radar Altimeter, the chirp scaling algorithm, and hybrid-polarimetric SAR architecture. He is on NASA's Europa Orbiter Radar Sounder instrument design team. Dr. Raney is on the Science Advisory Group for the European Space Agency's CryoSat, a satellite-based radar altimeter based on his original ideas. Dr. Raney has an extensive background in imaging radar theory, and in interdisciplinary applications using sensing systems. He is the author of over 400 journal and conference articles, and ten book chapters, including “Remote Sensing Space Based Radars”. Chapter 18 in the Radar handbook, 3rd ED. M. Skolnik, editor (2008).
