Forest backscattering observations by using particular polarimetric states
Polarimetric synthetic aperture radar (SAR) provides coherent information of the imaged scene in the form of the complex scattering matrix on a pixel-by-pixel basis. Full advantage could be gained from this representation if a polarimetric configuration could be identified as being characteristic of a particular target or of a particular physical state of the same target. Several techniques have been developed and applied in recent years to interpret and analyse the information content of polarimetric images acquired in this way. In all cases, the final objective was to improve the classification capabilities of the SAR images by characterising given sets of scatterers with certain known scattering behaviour. Target heterogeneity and degrees of polarisation have been explored and a tentative description of polarimetric scattering mechanisms has been given by modelling the forest interaction with the impinging radiation as a single or double bounce scattering. In this paper preliminary results are presented which were achieved by analysing polarimetry data acquired over the Black Forest test site in south Germany, during the Multisensor Airborne Campaign held in Europe in 1991 (MAC-Europe '91).
