A Sea Clutter Suppression Method Based on Machine Learning Approach for Marine Surveillance Radar
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Marine surveillance radar is widely used in marine monitoring for its ability of observing sea surface all-time and all-weather. However, the radar target detection performance is seriously affected by the existence of sea clutter.

Modeling the Amplitude Distribution of Radar Sea Clutter [PDF]
Remote Sensing, 2019 Ship detection in the maritime domain is best performed with radar due to its ability to surveil wide areas and operate in almost any weather condition or time of day. Many common detection schemes require an accurate model of the amplitude distribution of radar echoes backscattered by the ocean surface. This paper presents a review of select amplitude

Statistical analysis of bistatic and monostatic sea clutter
IEEE Transactions on Aerospace and Electronic Systems, 2015 In this work, we analyze the sea clutter data collected simultaneously by the bistatic and monostatic nodes of an S-band netted radar system under different out-of-plane geometries. The empirical distribution of sea clutter data are fitted to some known heavy-tailed distributions, and the sea spikes statistics are examined.
