Introduction into SAR Interferometry

Kurzfassung

The tutorial introduces the basics of SAR interferometry. It presents the different application areas and processing techniques ranging from DEM generation over subsidence measurement to moving target indication. The concept of coherence is introduced and the major error sources that lead to decorrelation or systematic phase effects are shown. Distributed scatterers and the associated problems of wavenumber shift and volume decorrelation are explained. An overview of current space borne systems together with an outlook on future systems is given.
