摘要：Digital SAR imagery become more and more subject of scientific data evaluation. At the samethere is an increased need for radar image simulators to be used in preparation for future SARmissions. Therefore, the authors initiated an investigation to study the information content of SIR-Bdata from a well known test-site in comparison to available TM data and, furthermore, to measurethe quality of a radar image simulation in the face of real, validated SAR data. Based upon TM datafrom july 1984, covering a pari of the Rhine valley, a detailed classification with respect to treespecies and natural age classes of the forested area was performed and verified against availableground truth. More categories such as vineyards, towns etc. were determined by an interactiveclassification of the TM data in comparison to a topographical map. Two SIR-B data sets fromOctober 1984, covering the same area, however under different geometrical conditions, were alsoavailable. Furthermore, there was access to a digital terrain model (DTM) of the common TM/SIR-Bkernel area, which means that in conjunction with the TM derived classification the input data setsfor a radar image simulation package were available.Thus a manifold data set was produced and used for an extensive data comparison procedure,especially with respect to a detailed statistical examination. A direct comparison between TM andSIR-B data was made regarding the ability for forest classification. The geometrical influence onradar data was examined. Simulated data and SIR-8 data were compared to value the statisticalapproach within the simulator.The paper presents in detail the investigation approach as well as the discussion of the results
