Abstract
To address scanning radar forward-looking sea imaging, this paper proposed a super-resolution method based on Weibull distribution. The proposed method in our work introduced the generalized Gaussian distribution and Weibull distribution to represent the prior distribution of the target and the sea clutter respectively, which are more suitable for actual sea imaging. And the corresponding objective function was derived under the MAP framework. In order to overcome the objective function's nonlinearity, this paper adopt Newton-Raphson iterative method to resolve it. Finally, through simulations, which indicates that the proposed method has superior imaging performance compared with other traditional methods for sea imaging.
