This chapter forms an introduction to the techniques and ideas behind radar interferometry and its application to remote sensing. It provides a link between Chapters 1-4, which consider polarisation effects only, and Chapters 6-8, which deal with the fusion of polarisation with interferometry. It begins with a review of different modes, including across-track, along-track and differential, before considering in detail the relationship between interferometric phase and surface parameters such as elevation and displacement. The error in phase is then associated with coherence, and the various sources of loss of coherence in interferometry are reviewed. Special attention is paid to volume decorrelation, as this is a function of several important parameters in volume scattering, and a new approach based on a Fourier-Legendre series expansion is used to model arbitrary volumes.

Keywords: Radar Interferometry; Across-Track; Along-Track; Differential; Coherence; Volume Decorrelation; Temporal Decorrelation
