Figure 16

Simulated radiance/reflectance image of marine environment (sand, waters with sand bottom at 2 m & 8 m depths, panels of 1 m * 1 m & 2 m 2 m under water at 2 m & 0.2 m depth, chlorophyll of 3 mg/m3, sediment of 1.8 g/m3, and yellow substance of 0.6 g/m3) obtained with SIMGA model at 1.5 km altitude (spatial resolution 1 m VIS, 2 m SWIR, spectral resolution 2.4 nm VIS, 10.8 nm SWIR). Simulated synthetic reflectance (waters with sand bottom at 2 m or 8 m of depth, panels under water at 0.2 m and 1 m of depth, beach surface sand) from two-fluxes model (a), radiances at 1.5 Km altitude (b), surface reflectance (also beach sand and concrete pier are represented in the upper part of Figures 16(b) and 16(d)) after atmospheric inversion algorithm based on Modtran code with the same parameters as the direct simulation (d), and RGB synthetic radiance image representing the simulated scenario (c).
