Retrieval of Parameters for Three-Layer Media with Nonsmooth Interfaces for Subsurface Remote Sensing

Figure 4

Sensitivity of RCS to correlation length 𝑙 decreases significantly for larger values of 𝑙. The simulation was performed at 435 MHz. Simulation parameters: A = 3 cm, period = 1 m, 𝜎_rms=4cm, layer separation =  .5m, and 𝜖_𝑟1=5.5+.3𝑖.
