%X According to the imaging principle of Synthetic Aperture Radra and dack-scattering characteristics of snow, authors examined the capability of snow-cover mapping with multifrequency and multipolarized SAR images from SIR-C carried by shuttle. The result shows that C-band HH and W images can be used to discriminate between wet-snow and snow-free area, but there is a prolem to separate rock from dry snow; L-band HH and VV images are easily to separate snow-cover area from others; and cross-polarized SAR images of C L-bands can be used to discriminate betWeen dry-snow and rock. So it is possible to map snowcover using SAR data.
