Abstract

The target and sea clutter Doppler domains frequently overlap due to the frequent passage of slow ship targets through the sea clutter zone. In this letter, a novel sea clutter suppression method is suggested as a solution to this issue, whose key is a novel singular value zeroing criterion guided by the search results of two-dimensional spectral peaks. Verified by simulations, the method proposed can improve signal-to-clutter ratio (SCR) from −8 to 41 dB in the frequency domain and be more effective than the conventional SVD-FRFT (a method for joint application of singular value decomposition and fractional Fourier transformer) and improved SVD-FRFT.
