Small Target Detection within Sea Clutter Based on the Fluctuation Analysis

Based on the fluctuation analysis, a novel approach for target detection in sea clutter is proposed. The self-affinity and scaling behaviors of sea clutter is analyzed by using the mean fluctuation. The q order normalized slope of fluctuation curve, as the characteristic parameter, is suggested to describe the fractal property of the target and sea clutter. The tests on the real data show that the target could be clearly distinguished from the sea clutter background with the proposed approach.
