, 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-
