Abstract :
The fractal dimension of sea clutter is estimated and its multifractal features are analyzed in this paper. A new method based on the difference between multifractal spectra of sea clutter and target plus sea clutter is proposed to detect targets in sea clutter. The verification of real sea clutter shows that this method is useful and has low computation burden. So it provides a new idea and an effective method to detect low observable targets in sea clutter.
