Abstract There exist bound gravity-capillary waves that move at the speed of the dominate waves on the ocean surface, apart from free gravity-capillary waves that satisfy the linear dispersion relation. Based on the Bound\Free wave composite surface model (BF), a theoretical model to predict the Doppler bandwidths of bound and free waves is proposed in this paper. The numerical simulations and microwave experiments in the wind-wave tank are shown in this paper, to discuss their Doppler characteristics of bound and free waves under different wind speeds and radar frequencies.
