Abstract

Knowledge of sea clutter is of great significance in marine target detection and discrimination. In this paper, the wideband backscattering electromagnetic (EM) fields of two-dimensional (2-D) sea surfaces are numerically calculated employing the weighted curvature approximation (WCA) method. Monte Carlo trials are performed to investigate the influences of radar parameters on the statistical characteristics of the rang-resolved sea clutter. It is found that the sea clutter tends to be spikier with finer radar resolution, lower grazing angle, narrower beam width, and in the upwind direction. Meanwhile, the Pareto distribution is demonstrated to describe the statistics of the sea clutter intensities very well.
