MACHADO FERNANDEZ, José Raúl  e  BACALLAO VIDAL, Jesús de la Concepción. Statistical Distributions for Sea Clutter Modeling: A Survey. EAC [online]. 2017, vol.38, n.2, pp. 12-35. ISSN 1815-5928.

The sea clutter is a random interfering signal that appears in radar readings caused by the reflection experienced by the emission over the sea surface. After a deep review on the related literature, 23 statistical distributions or models were found for representing sea clutter. The authors classified these models into five groups taking into account the frequency of use and the importance of each distribution. The performed review has two main achievements. Firstly, the mathematical expressions for the distributions were gathered and unified, which contributes to the homogenization of the studies. Secondly, a wide set of candidate distributions were offered enabling the execution of new investigations related to the fit of statistical distributions to empirical clutter data. The investigation strongly recommends the use of 15 distributions, while common studies rarely used more than four.
