The Renaissance in Radar Remote Sensing -
New Vision for Earth and the Planets

Paul A. Rosen
Communication, Tracking, and Radar Division
Jet Propulsion Laboratory, California Institute of Technology, Pasasdena, USA




Abstract: The age of spaceborne radar remote sensing was born in 1978 with the launch of SEASAT, an experimental satellite carrying an array of microwave instruments – a radiometer, an altimeter, and a synthetic aperture radar.  Designed by NASA’s Jet Propulsion Laboratory, SEASAT demonstrated in its short lifespan the uniqueness and utility of radar’s all-weather day/night capabilities. Much as the rediscovery and repurposing of the knowledge from classical times led to the European Renaissance, the past decades since SEASAT have seen the repurposing of originally military technology and techniques toward a sustained and accelerating international growth in the number and variety of radar instruments that are orbiting Earth and the planets to understand where we live – a Radar Renaissance. Spacefaring nations now consider Earth imaging radar to be critical to their scientific and operational needs, and a growing number of systems are being launched around the world.  Radars of all varieties are producing essential climate records, with a scientific imperative for continuing measurements.
This talk presents an overview of the major developments in spaceborne Earth and planetary radar systems, with some emphasis on NASA/JPL missions.  The talk will highlight the intersections of science and innovation in spaceborne radar developments, including some of the most interesting science and technology achievements obtained over the years, and describe upcoming initiatives that support future directions in Earth and planetary observations.


Biography: Paul A. Rosen is Project Scientist of the ISRO-NASA Synthetic Radar Mission at Jet Propulsion Laboratory (JPL), USA. Dr. Rosen has been Principal investigator and co-investigator on a number of scientific research and computing tasks over the years. Hi is presently a JPL Senior Research Scientist.  Past positions at JPL include Manager of Radar Science & Engineering Section.
His assignments at JPL have centered on scientific and engineering research and development in methods and applications of Synthetic Aperture Radar (SAR) and interferometric SAR (InSAR). He was supervisor of the Interferometric SAR and System Analysis Group at JPL from 1995 until November 2002. Dr. Rosen has developed and promoted scientific applications of differential interferometry, including crustal deformation mapping and hazard assessment, and has led several proposals for surface deformation satellite missions.
Dr. Rosen was the Shuttle Radar Topography Missions (SRTM) Project Element Manager for Algorithm Development and Verification from 1996 to 2000, and was the SRTM metrology Tiger Team lead in 2001. From 2002 to 2004, he led a NASA-funded collaboration with the Air Force Research Laboratory, developing dual use L-band radar technology. Most recently, he has been leading joint (interagency) radar mission studies. Dr. Rosen is also a visiting faculty member and lecturer at the Division of Geological and Planetary Sciences at the California Institute of Technology, and he has authored or co-authored over 30 journal articles and two book chapters.
Prior to JPL, Dr. Rosen worked at Kanazawa University, Kanazawa, Japan, studying wave propagation in plasmas, and the dynamics and observations of Saturn's rings. As a post-doctoral scholar and graduate student at Stanford University, he studied the properties of the rings of the outer planets by the techniques of radio occultation using data acquired from the Voyager satellites, discovering new dynamical features in the rings of Saturn and Uranus.
Dr. Rosen is a Fellow of the IEEE, past-chair of the Metro Los Angeles Section’s Geoscience and Remote Sensing Society (GRSS) Chapter, and currently serves on the GRSS Administrative Committee.


Haystack Ultrawideband Satellite Imaging Radar (HUSIR)

Joseph Usoff
MIT Lincoln Laboratory in the Advanced Sensors and Techniques Group, USA




Utilization of the Earth orbital regime is growing at a rapid pace and space situational awareness (SSA) has become of great interest to all. A major component of SSA is characterization of unknown objects. Characterization includes assessment of orbit, size, shape, orientation and functionality. Imaging is a very useful mechanism to characterize objects and the primary metric of imaging capability is resolution. To characterize an object, it must be resolved into many resolution cells; therefore, resolution cell size must scale with the size of the object. To characterize small satellites, resolution of the order of a few centimeters is required.
Ground-based optics provide limited imaging capability of orbiting objects due to poor resolution at the ranges of interest and susceptibility to adverse weather. Ground-based inverse synthetic aperture radar (ISAR) imaging has several advantages over ground-based optical imaging. It is more tolerant to weather, resolution is not a function of range, and since it provides its own illuminating signal, it is available at all times of the day. Ground-based systems are less costly and are easier to maintain and upgrade than space based systems.
MIT Lincoln Laboratory developed the Haystack Ultra-wideband Satellite Imaging Radar (HUSIR) to provide high-resolution images of objects orbiting the earth. HUSIR is a large dual-band monostatic radar with an instantaneous bandwidth of 1 GHz at X band and 8 GHz at W band, thereby providing fundamental resolution of 25 cm at X band and 3 cm at W band. This presentation will review the HUSIR design and will highlight the challenges that were faced in implementing that design.


Biography: Joseph Usoff is a senior staff member at MIT Lincoln Laboratory in the Advanced Sensors and Techniques Group. Since joining Lincoln Laboratory in 1993, his research activities have included missile seeker testing, development of an automated RCS diagnostic tool for aircraft, development and implementation of real-time radar imaging algorithms, and development of the Haystack Ultra-wideband Satellite Imaging Radar (HUSIR). He earned a bachelor’s degree in electrical engineering from Carnegie-Mellon University and master’s and doctorate degrees in electrical engineering from The Ohio State University. He has previously worked at Raytheon as an antenna engineer, at the U.S. Air Force RATSCAT facility as the chief data analyst and at The Ohio State ElectroScience Laboratory as a graduate researcher.


Exploring the Ocean Floor with Synthetic Aperture Sonar

Roy Edgar Hansen, PhD
Norwegian Defence Research Establishment (FFI)
University of Oslo, Norway





Abstract: The ocean covers more than 70 percent of the surface of our planet. Detailed information of the seabed at large depths is increasingly important in many fields such as marine biology, marine geology, offshore constructions and installations, and military applications. With the advent of unmanned autonomous underwater vehicles capable of operating at large depths, there is a need for high performance imaging sensors, and synthetic aperture sonar (SAS) is becoming the tool of choice for very high resolution imaging and mapping of the seabed. Although not as sophisticated and mature as state-of-the-art in SAR, modern SAS is relatively capable, being ultra-wideband widebeam multi-element interferometric systems with theoretical geometrical resolution better than 3 x 3 cm. The ocean environment imposes challenges for the synthetic aperture technique. Accurate positioning is non-trivial in the absence of GPS and stable platforms. The sound speed can vary up to 3% and cause substantial refraction. In this talk, we describe the similarities and differences between SAR and SAS, and the particular challenges in SAS. We show example SAS images from various places for different types of applications.


Biography: Roy Edgar Hansen received the Ph.D. degree in physics from the University of Tromsø, Norway, in 1999. From 1992 to 2000, he was with the Norwegian research company TRIAD, working on multistatic sonar, multistatic radar, synthetic aperture radar, and underwater communications. Since 2000, he has been with the Norwegian Defence Research Establishment (FFI), Kjeller, Norway, working on synthetic aperture sonar. In the period 2009-2015, he was the research manager for the marine robotics development at FFI, including the fields of underwater navigation, battery and fuel-cell technologies, decisional autonomy, automated target recognition, and synthetic aperture sonar.
