Applicability of sea clutter models in nonequilibrium sea conditions

This paper presents the comparative analysis between the sea clutter models and the recorded data to evaluate the limitations of the models. The availability and applicability of these models in nonequilibrium sea conditions are discussed. The results show that these models underestimate sea clutter scattering coefficient in upwind and downwind conditions. In the strongly local crosswind conditions, the TSC model can obtain good match results by inputting separately parameters of wind speed and wave height instead of sea state number.
