Sea clutter scattering is analyzed in the paper. The stochastic differential equations are given for the physical quality of sea clutter. The diffusion process model is built by using Ito formula. These processes are represented as Ito stochastic differential equations, which enables the identificating their stochastic volatilities with certain free functions that serve as calibrating the model. Finally the correlation detection method is used to detect weak signal from sea clutter.
