N2 - The increase of small targets on the sea surface poses a great threat to public security. Sea surface has extremely complex scattering characteristics and sea clutter is mixed with radar target echoes, which seriously affects the detection performance of radar for small targets on the sea surface. Therefore, a method based on sea spikes identification and matrix completion is proposed in this paper. By analyzing the characteristics of sea spikes, the sea spikes in radar echoes are distinguished and eliminated from the original signals. Then, the unqualified data are filled up by matrix completion method, which effectively improves the signal-to-noise ratio of target signals. Finally, the validity of the method is verified by using measured data and simulation data.
