Abstract Synthetic Aperture Radar (SAR) images from the- National Aeronautics and Space Administration's Shuttle Imaging Radar-B (SIR-B) Mission were used to analyze the effects of radar incidence angle on information content and vegetation penetration. Three SAR data sets using incidence angles of 26°, 46°, and 58° were acquired over the mangrove jungles of Southern Bangladesh. The data sets were digitally processed using 3 × 3, 7 × 7, and 11 × 11 spatial filters and geometrically registered to a multisource-multilevel-corraborative data base consisting of Landsat data, forest map data, and in situ acquired forest enumeration and topographic information. Analyses revealed that significant vegetation "penetration" was found at all angles and that tree and canopy structural morphology may exert an influence on this phenomenon.
