| Abstract: | Taking into account the variations of the refractivity gradient near the sea surface, We have used the curved wave spectral estimation (CWSE) technique to calculate the grazing angle. CWSE combined with the modified GIT reflectivity model and radar range equation, the radar sea clutter power modeling is performed under the atmospheric duct propagation conditions. Finally, the validation of CWSE is tested through numerical experiments and comparisons with the real measurement data.
