SummaryThe main objective of this project is the investigation of dynamics, evolution and polarimetric properties of agriculture and soils within the four TERENO observatories in Germany. The observatories are highly equipped with a variety of in situ measuring sensors for soil and vegetation properties. In addition intensive ground measurement campaigns will take place within the observatories on a yearly basis, mostly within the vegetation growth period and coincident to the SAR data takes. The high resolution TerraSAR-X data will be recorded in StripMap mode and in dual polarisation (HH/VV) to support this task. The TerraSAR-X imagery can be also compared with other remote sensing sensors (hyperspectral and passive microwave) having different acquisition techniques, frequency, resolution and coverage. The extensive in situ data set and the TerraSAR-X data in dual polarisation (HH/VV) will build up a unique dataset for algorithm development directed towards soil and vegetation parameter retrieval at short wavelength. The dual-polarimetric observation space will be exploited using decomposition and inversion techniques based on electromagnetic scattering models suitable for short wavelength.Investigation and analysis of TerraSAR-X data will be done by DLR internal radar experts for parameter inversion. This work and the data costs are funded by internal research finances. Reference and in situ data will be provided by the external team members at no charge in exchange for SAR data.
