We describe the relations between the statistics of the speckled image I(x) that is produced by an astronomical object at the focus of a telescope and the statistics of the point-source speckle pattern S(x) that is obtained under comparable conditions of turbulence. We show that the characteristic function (CF) of I(x) can be written as a central slice of a(More)
This communication adresses the parameter estimation problem using the minimization of a Whittle-type criterion when the spectrum parametrization is linear versus the unknown parameters. In this case, the global convergence of a particular iterative minimization algorithm is proved. This estimation method applies to stellar speckle interferometry for the(More)
