Abstract
In the situation of high resolutions, high sea states and small grazing angles, the sea clutter amplitude distribution has heavy trailing part, this part has a significant impact on the sea surface target detection. This paper introduces a fusion method of sea clutter amplitude distribution model, based on which new amplitude distribution models of sea clutter can be designed, and thus the trailing part of the sea clutter amplitude distribution can be well fitted. Through the verification by using the sea clutter data of UHF, L, and S-band, it is indicated that the introduced fusion method can give a better fit in the trailing part of the sea clutter amplitude distribution than other conventional modeling methods. Further, for the amplitude distribution without heavy trailing part, this method also has a good fitness.
