Multilayer Brightness Temperature Tracing Method for Rough Surface Scene Simulation in Passive Millimeter-Wave Imaging

Figure 14

(a) Simulated image of Lambertian model. (b) Comparison between improved models with the Lambertian model. (c) Simulated image of improved model. In (a) and (c) the parameters of the four rough surfaces from left to right are, respectively, ( = 0.0003 m, = 1.6λ), ( = 0.15 m, = 10λ), ( = 0.0001 m, = 1.6λ), and ( = 0.1 m, = 10λ).
