In the frame of the Astronomical Validation and Early Science activities for the 64m Sardinia Radio Telescope (SRT, http://www.srt.inaf.it), we performed 6-22 GHz imaging observations of the complex-morphology SNRs W44 and IC443. We adopted innovative observing and mapping techniques providing unprecedented accuracy for single-dish imaging of SNRs at these frequencies, revealing morphological details typically available only at lower frequencies through interferometry observations. High-frequency studies of SNRs in the radio range are useful to better characterize the spatial-resolved spectra (and then physical parameters) of different regions of the SNRs interacting with the ISM. Furthermore, synchrotron-emitting electrons in the high-frequency radio band are also responsible for the observed high-energy phenomenology as -e.g.- Inverse Compton and bremsstrahlung emission components observed in gamma-rays, to be disentangled from hadrons emission contribution (providing constraints on the origin of cosmic rays).
