The use of radar-based methods for post-fire burn scar detection offers clear advantages over other sensor types: this part of the electromagnetic spectrum is generally unaffected by atmospheric effects, is sufficiently sensitive to vegetation structure and soil moisture, and its existing limitations can be readily minimized by incorporating optical data. The aim of this study was to investigate the potential of C-band synthetic aperture radar data for detecting burn scars on peat soils. Single-polarization and crosspolarization data were tested using the Ryazan Region as a case study. In addition, optical data and their combination with radar data were analyzed. The accuracy of the obtained results was assessed by comparison with field data. Our study showed that the combined use of the two spectral ranges increased the overall classification accuracy.
Keywords: remote sensing, peat bogs, peat fires, Sentinel-1, Sentinel-2, radar range, optical range
