## Abstract In this research, with a view to three‐dimensional image reconstruction, a method for tracking the coordinates of the tomographic image plane is investigated by drawing attention to the shift and variation of the speckle pattern in the B‐mode image. In this method, the shift vector in t

Speckle in radar images has the characteristic of a multiplicative noise. In this article, two unsupewised methods are introduced to estimate the speckle noise statistics using the mean and the standard deviation of small image blocks (4 x 4, or 6 x 6 pixels). Since most radar images contain many sm
