N2 - Sea clutter suppression is one of the major measures to improve target detection from sea clutter. Singular value decomposition-fractional Fourier transform (SVD-FRFT) filtering is conducted to suppress sea clutter without impairing the target even when the target and first-order sea clutter are mixed in the Doppler spectrum. However, for the range cells with only sea clutter, the SVD-FRFT filtering cannot thoroughly suppress the sea clutter owe to energy concentration of sea clutter to some extent in FRFT domain, which gives rise to false alarm in target detection. To address this problem, the combination of empirical mode decomposition (EMD) and SVD-FRFT is proposed to separate target from sea clutter and pre-suppress the sea clutter. The experiment based on real measured sea echo shows that the novel method can obtain superior performance.
