... determination of the thick-depth is estimated by values of the order of 10 m at the C-band. It means that lakeice does not fully absorb radiowaves longer than the C-band waves, and the thermalmicrowave ... covers the soil; ks, Ts, and Tos are the emissivity, the temperature, and the brightness temperature of the bare soil, respec-tively; Tv and are the temperature and the albedo of the vegetation, ... especiallyin the cases of C- and X-bands. Thus, we can conclude that P- and L-band radar ispreferable for soil moisture measurement; with regard to monitoring a grass canopy, the C- and X-band radar...
