SAR Offset Tracking

open access: yes, 2022
This chapter introduces various methods for offset tracking using SAR imagery. The chapter starts with a brief introduction to the acquisition geometry and the imaging method of SAR sensors, including a description of radar speckle. Equations for offset tracking in the spatial domain and the frequency domain are derived. Signal-to-noise ratio and cross-

Seven-year variation in glacier surface velocity at Narsap Sermia in Southwest Greenland

open access: yesGIScience & Remote Sensing, 2023
Glacier velocity is a critical factor closely related to ice dynamics of the Greenland ice sheet (GrIS). We present variations of ice velocity using space-based synthetic aperture radar (SAR) observations from July 2013 to September 2020.
