ملخص المقالة :
Sea Klatter is the rader reflection from water surface which can be detected by pulsating rader and it is a very complex part of radar klatter modeling. Many approaches for fitting sean klatter amplitude with statistical distribution functions have been done, but sea klatter nonstatinary characteristics makes it here impossible to complete fitting with distribution funcrions. So, The parameters of distribution function to be estimated and hence target detection from sea klatter is more complicated. In The recent years, The Tsallis distribution have been proposed for klatter simulation. This distribution function resulted from Tsallis entropy which is generalized form of shanen entropy. Two main short comes of the Tsallis simulation are: First, short step size parameters estimation and long time comsuming; second, low target detection accuareey. Main Contribution of this paper increasing of step size for parameters estimation and improving target detection accurecy with using full samples set.
