Abstract

To detect weak sea target effectively, the method based on wavelet leaders multifractal (WL-MF) was studied. Wavelet leaders was used to analyze the multifractal characteristics of sea clutter, the multifractal parameters of sea clutter and target area were extracted to detect target. It is verified by IPIX radar sea clutter data. Result shows that scaling function and multifractal spectrum have the ability for distinguishing target from clutter under different sea conditions. In comparison with traditional multifractal detrended fluctuation analysis, the WL-MF method needs less computation and is easier to carry out.
