Detecting the Depth of a Subsurface Brine Layer in Lop Nur Lake Basin Using Polarimetric L-Band SAR

Figure 4

Two-layer structure and scattering mechanisms, where stands for complex dielectric constants, is the thickness of layer 1, represents Fourier transformation of surface correlation function, and are RMS height and correlation length, respectively, a is albedo, means extinction coefficient, and and accounts for incidence and transmission angles.
