| Abstract | The basic imaging geometry of the SAR is considered for the study of trail and road detectability in imagery of rainforests with no significant topographic relief, as a function of the SAR parameters
and trail (or road) widths and their orientation relative to the SAR viewing direction. The results are confirmed experimentally on a dense forest site in the south of Sumatra, Indonesia, using the multi-resolution capability of Radarsat. The best
trail detectability was obtained with the fine modes at the highest incidence angle. The use of both ascending and descending fine modes permits even the detection of 5 to 6 m wide trails under particular conditions. The same trails could not be
detected using JERS-1 satellite SAR of coarser resolution. The resolution dominates trail detectability and the use of a longer wavelength (L-band for HERS-1) does not allow the resolution of narrow trails. |
