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
