Abstract Based on deeply analyzing wave-current interaction equations and radar backscattering model of ocean surface, it developed a calculating model of radar backscattering coefficient caused by wave-current interaction on ocean surface.Then the model is compared with the well known Alpers' s model through numerical test on calculating radar backscattering coefficient perturbation caused by ocean surface non-even current fields.Furthermore it provided the statistical and analyzing results of the two models' coherence degree. The results show that the two models are coincident.Thus this paper' s model can be regarded as a numerical model to study radar' s ability for detecting ocean surface non-even current fields.
