Abstract

The paper considers methods of elimination of diffraction distortion in radio-engineering imaging systems with sparse antenna arrays. At the first stage the problem of synthesis of antenna array geometry is resolved, while at the second — processing of images is performed by the nonlinear method with constraints. The paper includes results of imitative simulation of the process of creation and reconstruction of images in the radiometric system.
