Day 3 Session 1: Introduction to Radar Interferometry and Its Applications
Overview:
Radar interferometry is one of the most powerful remote sensing techniques with applications to such diverse areas as topography measurement, geophysics of the solid earth and cryosphere and to ecosystems. This one-day course will provide an introduction to radar interferometry and its applications. We will begin with a brief review of radar and SAR imaging principles followed by the basics of interferometry for both topography measurement and of differential interferometry for measuring surface change and deformation. We will cover interferometric measurement techniques, interferometric phase and correlation, interferometric sensitivity equations for topography and deformation, error sources and limitations of the techniques. Principles and applications will be illustrated with examples from both spaceborne and airborne systems. Finally, advanced concepts such as polarimetric interferometry and tomography will be briefly introduced.
Instructor:
Scott Hensley, Senior Research Scientist, NASA Jet Propulsion Laboratory
Scott Hensley received his BS degrees in Mathematics and Physics from the University of California at Irvine and the Ph.D. in Mathematics from Stony Brook University where he specialized in the study of differential geometry. In 1991, Dr. Hensley joined the staff of the Jet Propulsion Laboratory where he is currently a Senior Research Scientist studying advanced radar techniques for geophysical applications. He has worked on the Magellan and Cassini radars, was the GeoSAR Chief Scientist, lead the SRTM Interferometric Processor Development Team, lead a team using GSSR data to generate topographic maps of the moon and was Principal Investigator and is currently the Project Scientist for the NASA UAVSAR program which is an airborne electronically scanned L-band radar designed for repeat pass applications. Most recently he has been very active in developing proposals for exploring the solar system that require radar observations.
