英文摘要	This chapter provides an introduction to radar sounding and imaging of the polar ice sheets and the application of Interferometric Synthetic Aperture Radar (InSAR) for ice dynamics and topography measurements. It begins with a brief review of the electrical properties of ice that are important to the design of radars for sounding ice and interpreting results. The chapter discusses the trade-offs between radar resolution and the signal-to-noise ratio, and the approaches used to improve the signal-to-noise ratio via hardware and software techniques. It also explains the use of SAR processing and pulse compression in a radar for improving along-track resolution and obtaining the high sensitivity required to sound ice around ice-sheet margins. The chapter presents a brief overview of antenna arrays and their use on both short- and long-range aircraft. Finally, it describes the principle of InSAR operation, the steps involved in generating InSAR images, and measurement errors. © 2015 by JohnWiley & Sons, Ltd. All rights reserved.
