Abstract: In recent years, the high-sensitivity and wide-field extragalactic radio continuum surveys conducted using the most powerful radio interferometric facilities, including the Karl ,G. ,Jansky Very Large Array (VLA), Low Frequency Array (LOFAR), Giant Metrewave Radio Telescope (GMRT), Murchison Widefield Array (MWA), Australian Square Kilometre Array (SKA) Pathfinder (ASKAP), MeerKAT (SKA precursor at South Africa), etc., have provided us with unprecedented insights in a wide range of astronomical fields, including the formation and evolution of galaxies. In this talk, I will introduce some very successful extragalactic radio continuum surveys and our recently-completed projects on studying the radio spectral properties of star-forming galaxies based on these surveys. I will also discuss how the high-quality radio surveys at both low and high frequencies from the SKA and its precursors will shed light on galaxy formation and evolution through the radio window.
