  The present work discusses the development of the radio technique for
detection of ultra-high energy air-showers induced by cosmic radiation, and the
prospects of its application in the future multi-messenger activities,
particularly for detection of ultra-high energy cosmic rays, gamma rays and
neutrinos. It gives an overview of the results achieved by the modern digital
radio arrays, as well as discuss present challenges and future prospects.}
