This course explains basic principles and applications of Synthetic Aperture Radar (SAR) imaging radar. A primary goal of the course is to reveal the fundamental operating principles, basic phenomenology, sample processing algorithms, and performance capabilities and limitations of this valuable remote sensing technology. This will include issues and trade-space in system engineering, design, and performance prediction. Applications and exploitation techniques will be presented, including topographic-mapping Interferometric SAR, Coherent Change Detection, Polarimetry, and Slow-Motion Detection (VideoSAR). Example systems and image products will be generously presented to illustrate the instructions. This course intends to answer the questions "What is SAR?" “Why SAR?” "How does it work?" "What can SAR do?" and "How well can SAR do it?"
