Dual-polarimetric agricultural change analysis of long baseline TanDEM-X time series data

摘要

Although the standard TanDEM-X baselines have been designedudto optimize the high resolution global Digital ElevationudModel (DEM) generation, during the Science Phaseudof the mission longer baselines are available. This allowsudinterferometric measurements with a higher vertical sensitivity,udwhich may make its use for agricultural applications,udwhere the crop heights are too small to be properly detectedudand analyzed with the standard baselines, more appropriate.udThis paper evaluates the use of the experimental long baselineudTanDEM-X acquisitions for the monitoring of the agriculturaludchanges in dual-pol single-pass interferometric time series.
