Modeling and Simulation of Correlated K-Distributed Sea Clutter Based on ZMNL

摘要

Researches on sea clutter are of great significance for the detection of targets on the sea in complex clutter background. Correlated Kdistribution is often offered as a non-Gaussian distribution model which can well describe the characteristics of radar sea clutter. Whether the clutter model is accurate and flexible or not, is an important criterion accessing the performance of radar signal simulator. Researches on modeling and simulation of clutter are helpful for the design of radar signal simulator and radar system. In this paper a method for modeling and simulation of sea clutter is proposed, correlated K-distributed sea clutter is then simulated by employing zero memory non-linearity (ZMNL) transformation based on the autocorrelation functions of K-dislribution and Gaussian distribution. Results demonstrate the approach is accurate, effective and feasible.
