Abstract
Wind fronts in SAR images can be investigated by combining a Bragg model for the backscatter cross section with a kinematic wind front boundary condition. However, it is shown that in order to apply the method, the backscatter should vary as a power of the wind speed. The method is illustrated on wind fronts observed during NORCSEX´91
