Improvement of primary radiometric images quality in scanning radiometers of compensation type

V.V. Pavlikov
Annotations languages:

Possibility of improvement of primary radiometric images quality formed by scanning radiometric devices of compensation type with using weight processing of the field amplitude-phase distribution in the antenna aperture by window functions (classical and Kravchenko functions) is investigated. For a quantitative estimation of similarity restored and true images the following metrics are used: mean absolute error, SSIM, DSSIM. Reasonability of using Kravchenko weight functions synthesized with using atomic functions of family fupN in the considered problems is substantiated.
