WebWhat is the Fisher information for a Uniform distribution? If X is U [ 0, θ ], then the likelihood is given by f ( X, θ) = 1 θ 1 { 0 ≤ x ≤ θ }. The definition of Fisher information is I ( θ) = E [ ( d log ( f ( X, θ)) d θ) 2]. WebFor a three-dimensional wide-angle synthetic aperture radar (SAR) with non-uniform sampling, it is necessary to divide its large aperture into several small sub-apertures before imaging due to the anisotropic characteristics of the target. The existing sub-aperture partitioning methods divide the aperture with equal intervals. However, for the non … import variables from /styles/variables.scss
