“…The results show the potential of TOPSAR data for ocean bathymetry reconstruction where TOPSAR L HH band backscatter across bathymetry signature pixels agrees satisfactorily with previous published results (Vogelzang et al 1992;Inglada and Garello 1999;Marghany et al, 2007). This is due to the fact that the ocean signature of the boundary is clear in the brightness of a radar return, since the backscatter tends to be proportional to wave height (Vogelzang et al 1992). In Cband with VV polarization, this feature is clearly weaker than at L-band with HH polarization.…”

“…They found that a single set of coefficients derived from a set of IKONOS images produces the good performance with an aggregate RMS error of + 2.3 m which is higher than bathymetry retrieved from SAR (Hesselmans et al 2000). Coastal bathymetry mapping by using optical remote sensing data, however, can be only fully utilized in the clearest water, and considerably less in turbid water (Vogelzang et al, 1992). Indeed, as the different wavelengths pass through the water column they become attenuated by the interaction with suspended particles in water (Mills, 2008).…”

“…In case of microwave imagery, radar observes the backscattered variations from the sea surface, e.g. roughness caused by modulations in the wave spectrum with respect to the surface current [11]. Such variations in the current velocity at the ocean surface can be recognized because of interactions between tidal flow and bed topography.…”
