Radio surveys at frequencies of ∼ 1 GHz allow to map the synchrotron emission (SE) in a frequency range where (except for very low Galactic latitudes or towards localized regions) it dominates over the other radio components. New all sky total intensity and polarization data at 1.4 GHz have been recently collected.We focus on the Galactic radio emission correlation properties described in terms of angular power spectrum (APS).We present for the first time the APS, in both total intensity and polarization modes, for some representative Galactic cuts and suitable APS power law (PL) parametrizations.
