Dependency of SAR Image Structure Descriptors with Incidence Angle

Kurzfassung

The interpretation of the structure in Synthetic Aperture Radar images depends by the used parameters and incidence angle. The evaluation is done on the high resolution SAR data and the interpretation is realized automatically. In this paper, we propose to study and asses the behavior of the primitive feature extracted methods for images of the same scene with 2-3 look angles covering the min-max range of the sensor. The tests are done on TerraSAR-X products High Resolution Spotlight mode at 3 m resolution and two sites were found that are appropriate for this. To identify the best features and appropriate incidence angle for them the Support Vector Machine and as a measure of the classification accuracy the precision –recall were considered. The precision-recall was computed first for all investigated features and after that the best were taken into account for the incidence angle evaluation.
