| Resumo | This paper describes a study performed to assess the suitability of multiband SAR data for discriminating stands of macrophytes with differences in height and density. In this study L band HH JERS-1 SAR and C HH band CCRS SAR 580 data were acquired for the Tucurui reservoir in March 7, 1994 and April 14, 1992, respectively. In spite of the two year difference in data acquisition, both sets were obtained during the beginning of the rising water season. Therefore it was assumed that differences in the detection of macrophyte stands and dead tree trunks were related to changes in the microwave interaction between macrophyte canopy in the L and C band. The SAR data were georeferenced and resampled to 12 m by 12 m resolution. The SAR data were submitted digital processing as follows: image filtering, contrast enhancement to produce a multiband composition in which differences in color were related to stand height and density. Aerial photographs were used for selecting macrophyte stand classes and the following image variables obtained: average digital number and standard deviation. The digital data for both L and C band were normalized against the mean digital number obtained for water surface since absolute calibration data were not available. The results show that band C is more sensitive to differences in the macrophyte canopy height and density than L band data. |
