High-order fractal characterisation of sea-scattered signals and detection of sea-surface targets

摘要

A novel method for identifying radar targets and clutter is presented. Instead of the traditional fractal dimension, the lacunarity, which is a high-order fractal feature, is used in this method. The formula for lacunarity in additive noise is also given. The experiments show that higher detection accuracy can be obtained by using the lacunarity feature than by using the fractal dimension.
